APR Presents the Oil Catch Can for MQB platform 1.8T and 2.0T

Posted on July 13, 2015 – 12:51 pm

APR is pleased to present the ultimate Oil Catch Can system for MQB platform 1.8T/2.0T engines.

The APR Oil Catch Can System is designed to prevent excessive crankcase oil vapors from entering the intake system while the engine is under boost. In doing so, the system helps reduce oil pooling in the intercooler hoses, carbon buildup on intake valves, and the decrease in octane caused by oil vapors.

Quick Facts:

  • Drains in seconds No need for tools, removal/disassembly to drain the can.
  • Four-stage baffling system Excellent oil droplet capturing properties.
  • Compact, two-piece billet design Easy disassembly for recommended annual cleaning.
  • Abrasion resistant Buna-N lines Resists oil degradation, kinks and abrasion with an OEM appearance.
  • OEM Norma fittings Makes install and removal simple with an OEM appearance.
  • Discrete hose routing Hoses are routed out of sight for an attractive install.
  • EA888 MQB Compatible Fits all 1.8T/2.0T EA888 Gen 3 MQB vehicles equipped with APR’s Carbon Fiber Intake System.
  • Catches oil Oil pools in the can, not in the intercooler piping.
  • Reduces carbon buildup Fewer oil vapors entering the intake tract helps reduces carbon buildup on the back of intake valves.
  • Increase performance Helps to reduce airflow restrictions and octane robbing oil vapors.


 

System Overview

During an engine’s combustion process extreme cylinder pressure is created. Some of this pressure ultimately becomes “blow by” gasses when it escapes the seal of the piston rings. As a result, crankcase pressure is generated and to prevent damage this pressure must be vented. Thanks to boost pressure, turbocharged engines produce more cylinder pressure than naturally aspirated engines. In turn, the requirement to effectively manage crankcase pressure is increased. More so, an increase in horsepower over stock comes through an increase in cylinder pressure, exacerbating the issue even further.

The factory system alleviates the pressure through a positive crankcase ventilation system, or PCV. Under light engine load, the PCV uses vacuum to help draw the gasses out of the crankcase and utilizes a cyclonic separator to draw the oil out of the gas. During heavy engine load, when boost pressure is present, that portion of the PCV is blocked off via a check valve and the gasses are sent directly to the inlet of the turbocharger. During this stage, little separation occurs and significant oil vapor is allowed to enter the intake tract which can cause the following:

  • Reduction in performance caused by a decrease in octane from oil vapors mixing with air/fuel mixture.
  • Reduction in performance caused by a decrease in airflow from excessive carbon buildup on intake valves.
  • Pooling of oil in the turbo, intercooler, intake tract hoses and manifold.

NOTE: Despite the popularity of deleting it, APR’s Oil Catch Can retains the factory PCV. Pulling vacuum on the crankcase is ideal as it helps ensure that all necessary gases escape. However, the factory unit incorporates a check valve that sees boost pressure. If that valve fails a boost leak would occur, decreasing engine performance until the valve was replaced. To date, APR has not seen a PCV check valve failure on any Gen 3 TSI engine. With the factory valve in place, it is also possible that some oil enters the intake tract through the cylinder head. However, most goes the way of the catch can and is subsequently captured. Though APR has had positive results retaining the factory PCV, the desire to replace it is understood and APR will be releasing a factory PCV delete that connects flawlessly to our catch can.

The APR Oil Catch Can System:

APR’s Oil Catch Can system installs between the PCV’s outlet and the inlet to the intake system and is designed to catch unseparated oil vapor. The supplied bracket and scratch resistant gasket allow the system to be installed on the required APR Carbon Fiber Intake System. This enables compatibility with all applicable MQB platform 1.8T/2.0T engines. The supplied hoses then connect and route out of site, for a clean and attractive install.

Unlike many catch can designs on the market, the APR system utilizes a track-proven four-staged baffling system. The baffles cause oil to pool at the bottom of the can, rather than the intercooler hoses. APR’s brutal track testing has proven the system works as designed, catching oil in the can and leaving the return hose clean to the touch!

Removing the oil is a cinch! No tools or can removal/disassembly are required thanks to a quick drain valve and hose conveniently located at the bottom of the can. Furthermore, servicing the can is simple, thanks to the billet two piece design.

The APR Oil Catch Can is a must have for customers interested in maintaining peak performance and keeping their intake tract and valves cleaner for the life of their vehicle.

Requirements: The APR Oil Catch Can system requires an APR Carbon Fiber Intake System for install.

APR Presents the VW (B6) Passat, CC, and Tiguan (FWD) Cast Downpipe Exhaust System!

Posted on May 26, 2015 – 2:21 pm

Upgrading the restrictive factory downpipe with the APR Cast Downpipe Exhaust System is a great way to increase performance and add a sophisticated growl to the exhaust note. Ideal performance is achieved through expelling exhaust gasses at maximum velocity through APR’s proprietary, low-turbulence, investment cast downpipe. Designed and assembled in-house, the system utilizes only premium materials and world-class manufacturing techniques to deliver unmatched quality and reliability.

apr exhaust universal cast downpipe system assembled fwd 1 midapr exhaust universal cast downpipe system assembled fwd 2 mid

Quick facts:

  • Designed and assembled in-house.
  • T304L stainless steel construction.
  • Argon back-purged TIG welding.
  • Investment cast downpipe.
  • 80mm inlet with integrated o2 bung and flange.
  • Low profile, sealed/corrugated flex section.
  • 76mm outlet with integrated bracket.
  • 8mm billet bracket.
  • 76mm brushed and de-burred piping.
  • Non-swedged/slip-fit/flanged piping.
  • Investment cast o2 bungs with billet plugs.
  • 300 cell, 100mm x 100mm GESI catalyst.
  • OEM-style slip-on clamps.
  • Reducer for OEM catback compatibility.
  • OEM gasket.
  • APR Stage II ECU Upgrade price waived.
  • Limited lifetime warranty.

The factory downpipe system consists of smaller, 63mm piping with varying bends and multiple restrictive high-cell-count catalysts, all of which contribute to a less than ideal flow path and hindered performance. APR’s engineers took a multi-step approach to maximizing flow, reducing under hood temperature, and eliminating unnecessary restrictions.

Detailed component photos and information

The APR Cast Downpipe Exhaust System is a complex system designed to deliver maximum performance. Each component was designed and developed with the absolute best in performance, strength, reliability and quality in mind.

Cast Downpipe Inlet and Outlet

The exhaust system features a strong, investment cast, T304L inlet and outlet designed to maximize flow and minimize turbulence. By casting the inlet, APR’s engineers were able to create a smooth and high-flow exhaust path that maximized flow through swept blends and shapes that are otherwise not possible through conventional fabrication techniques. The inlet perfectly matches the factory turbocharger’s 80mm outlet and gradually necks down over a long distance to further enhance performance. The mounting flange, oxygen sensor bung and bracket are integrated into the casting, and TIG welding at the flex section ensures a clean inner surface eliminating turbulence, vortices and eddies to the highest degree.

With a nominal wall thickness of 2.55mm the downpipe is strong and produces a refined exhaust note compared to thin wall tubing systems. The cast sections undergo a tumbling process to smooth and de-burr any imperfections inside the pipe, while simultaneously enhancing the exterior finish. Lastly, all necessary surfaces are CNC machined for an accurate fit.

Flex Section

APR’s engineers specified a T304L stainless steel, OEM-style flex section that is fully sealed with a corrugated inner lining to improve flow and reliability. The low profile design and minimal use of bradding material eliminates clearance issues common with other designs that can billow, rub, rattle and fray over time.

Bracket

Designed to stand the test of time, the bracket is CNC machined from 8mm-thick billet T304L stainless steel and the hanger feet are threaded into place, eliminating the need for welds. Weight is removed from the bracket, wherever possible, while not hindering its structural integrity. The bracket attaches to the cast downpipe’s integrated mounting bracket, and CNC machined spacers enable compatibility across multiple vehicles.

Piping

The APR Downpipe Exhaust System features premium grade T304L stainless steel for its excellent appearance, strength and corrosion resistance properties. The pipe is rolled to the 76mm European standard diameter with a 1.5mm wall thickness and a seemingly non-existent weld seam.

Pipe is cut to length in-house via APR’s CNC-controlled bandsaw to an accuracy of .25mm, ensuring a precise fit. Each pipe is de-burred, and the exterior finish is brushed to give the exhaust piping a clean and attractive appearance worthy of the APR name. APR’s fabrication team uses argon back-purging during the welding process, leaving a clean and smooth interior surface, and TIG welding for strength and appearance. Lastly, no swedging or slip-fitting is necessary due to APR’s OEM-style clamp design, leaving smooth and less turbulent connection points.

Clamps

APR’s engineers specified a T304L stainless steel, OEM-style exhaust clamp designed to eliminate the need for flanges, swedging, or slip fittings. By using this low profile design, the exhaust system can be positioned higher in the exhaust tunnel and away from the ground with better clearances compared to flanged setups. Each clamp allows for less turbulence and greater accuracy at the connection points as the pipes simply butt up to one another rather than the ambiguity and voids associated with swedged slip fittings. Furthermore, the clamp doesn’t rely on deforming the pipe to provide a tight seal, making install and removal more convenient.

O2 Sensor Bungs

APR’s Engineers paid special attention to the details when designing the APR Cast Downpipe Exhaust System all the way down to the oxygen sensor bungs. APR’s O2 bungs are investment cast from T304L stainless steel and are curved to perfectly fit on 76mm piping, without protruding into the pipe, as this would further impede airflow beyond the sensor itself. The bungs are TIG welded to the piping and back-purging is used to ensure the interior surface is smooth and clean. Lastly, a billet T304L stainless steel bung plug is included to cap off extra ports not needed on some models.

Catalyst

APR’s engineers specified a high-quality and high-flow GESI metal 300-cell catalyst ideal for forced induction application. During dyno testing, the 100mm x 100mm design showed no measurable loss in power, thanks to the catalyst’s specifications.

Internally the catalytic converter features a proprietary blend of precious metals and loading technology that helps to reduce emissions and smell common on cat-less setups. With performance in mind, the catalyst is placed far away from the turbo outlet to reduce turbulence in the downpipe and to help reduce under-hood temperature. The low-profile catalyst features a fully captured substrate brick, which is furnace braised to the outer mantle and physically captured by the diffuser cones preventing rattling, rotation, and damage to the substrate. Subsequently, a byproduct of running the catalyst is a reduction in noise, making the system as a whole more pleasing to the ear.

Reducer

A simple and removable, T304L stainless steel reducer, featuring a smooth transition, is included, making the APR Cast Downpipe Exhaust System directly compatible with the OEM catback exhaust system.

Gasket

Included with each system is an OEM gasket, designed to mate between the downpipe and the turbocharger.

The APR Difference

The Engineering and Designing Phase

In the past APR worked with other manufacturers to develop a limited range of private-label exhaust systems outside the scope of APR’s internal development and manufacturing capabilities. Understanding the limits of such a program, combined with APR’s desire to deliver higher-quality products in a timely manner with better customer support, APR invested in internalizing the program. With the release of this exhaust system and the others like it, APR is pleased to present our first systems fully designed and engineered in-house from the ground up!

Design and development begins with the use of APR’s professional grade in-house coordinate measuring machines. APR’s engineers have full access to a Romer Absolute arm with integrated laser scanner, FaroArm and Creaform 3D laser scanner for collection of special constraints surrounding the factory exhaust system. The engineers scan the vehicles and create detailed 3D maps of their design environment while designing each system in PTC Creo 3.0 CAD software.

Using APR’s in-house stereolithography 3D printer, rapid prototypes are created for fitment on the vehicle. The design is easily and quickly verified, and if necessary, changes can be made. Once adequate clearances and fitment is confirmed, especially in areas that move under load, physical quick-cast prototypes are created and fitted for final verification through real-world use.

APR’s world-class manufacturing partners from around the globe are responsible for manufacturing each component that falls outside of APR’s internal capabilities. Working closely with each manufacturer, APR’s engineers supply CAD models, materials specs, and other design specifications and work hand-in-hand with the manufacturer to develop the components. The end result is a collection of components, wholly unique to the APR name, awaiting final finishing, assembly and quality control at APR’s 78,000 square foot facility in Opelika, Alabama in the USA.

The Fabrication, Finishing and Assembly Phase

Manufacturing takes place both internally and externally to APR while finishing and assembly is completed in-house. APR’s fabrication team cuts, brushes and de-burrs premium grade T304L stainless steel piping for use in each midpipe. Then each cast component is sent through the ceramic vibrating tumblers to smooth and de-burr surface imperfections. Each component is then cleaned by hand and prepared for assembly.

APR’s fabrication experts TIG weld each component, creating reliable, high quality and attractive welds. Each component is back-purged with argon during the process ensuring the weld is strong and consistent, as well as clean throughout. With this process complete, the APR Cast Downpipe Exhaust System is born!

Final Quality Control

APR has placed a large emphasis on improving quality control across various product lines, and the exhaust program is not excluded. To ensure the systems are delivered as advertised, APR’s engineers have taken a multi-step approach that encompasses many techniques that go beyond the industry standard.

Metallurgy Testing

APR’s engineers request full metallurgy reports with each batch of components to ensure the components are made with the T304L stainless steel grades specified on the original design prints. This information is then cross-referenced against randomly selected and independently tested samples before the components are released for assembly.

Dimensional Inspection

Great designs only matter if the manufacturer delivers the components as expected. To help ensure the designs are as specified, APR’s engineers randomly select components and conduct full dimensional inspections using in-house 3D laser scanning equipment. Tolerances are digitally checked against the original specifications and passed or failed based on the results.

Fixtures

Operating in an environment designed for accuracy and repeatability, APR’s fabrication experts leave little room for error during the final assembly phase. Jigs and fixtures, created in-house, live on custom-specified fabrication tables featuring repeatable indexing holes and extremely flat surfaces. This working environment ensures the highest level of quality control during the assembly process and safeguards against dimensional variations potentially created during the manufacturing process. The end result is a system that fits every time as it’s true to the original design specifications.

Visual Quality

When hand-building the products in-house, an extra level of control takes place. Components are visually checked for imperfections, and items that fall out of quality standards are rejected. The products are then packaged with care before being distributed across the world.

APR’s confidence in the system’s quality allows for a limited lifetime warranty.

APR Presents the 1.8 TSI Generation 3 ECU Upgrade (Tiptronic Now Supported)!

Posted on May 13, 2015 – 1:14 pm

+66 HP, +99 FT-LBS of torque and 1.2 seconds off the quarter mile with APR’s newly released ECU upgrade for the 1.8 TSI Tiptronic Volkswagen Beetle, Jetta, and Passat make it by far the best bang-for-buck upgrade available! No appointment necessary, just roll through between 9am and 4pm, Monday through Friday!

 

APR is pleased to present the ultimate engine control unit (ECU) upgrade for the 1.8T EA888 Gen 3 engine. APR’s ECU upgrade is available in octane-specific variations and is conveniently flashed to the vehicle’s factory ECU through the OBD-II port without any physical modification to the factory ECU.

The ECU’s Simos 12 engine management system is responsible for proper operation of the engine during constantly changing environmental and load conditions. With built in compensational data for environmental variables and varying load conditions, the factory ECU is far more complex and intelligent than units found in other vehicle makes and marques.

APR’s Calibration Engineers spent months calibrating the engine management system, including many hours of chassis dyno development. With a thorough understanding of the ECU’s torque structure, APR’s Calibration Engineers properly increased engine load to produce more power and torque across the entire power band. APR’s ECU Upgrade increases boost pressure, optimizes ignition timing, cam timing, lambda and more to produce higher output!

APR’s ECU Upgrades provides an excellent leap in horsepower and torque while retaining OEM knock control sensitivity and other built in safety features. This results in an exciting and powerful upgrade, optimized for various fuel grades found around the world.

APR Stage I ECU Upgrade

The APR Stage I ECU Upgrade is designed to work without requiring other changes to the vehicle’s hardware. With the ECU Upgrade alone, APR’s Calibration Experts measured higher peak figures of 293 ft-lbs of torque and 242 horsepower with 93 AKI octane fuel. Large gains were seen throughout the power band, including an additional 99 ft-lbs of torque and 68 horsepower. The increase in power directly translates to an exceptionally quicker vehicle. Using advanced GPS measuring devices, APR’s engineers conducted several acceleration tests. During the 100-200 KPH sprint, the APR Stage I equipped vehicle crossed the finish line 9.845 seconds quicker, resulting in an outstanding 35% improvement!

Acceleration Enhancements:

Beyond horsepower and torque enhancements, APR’s Calibration Engineers were able to increase the acceleration rate of the vehicle through other calibrations changes. Ignition delay is reduced resulting in a more responsive pedal without altering overall throttle sensitivity. Furthermore, throttle lag commonly noticed at slow speeds and while reapplying throttle has been reduced.

Fuel Economy

APR’s Calibration Engineers paid close attention to several parameters directly related to fuel economy, especially while cruising at highway speeds. Depending on driving style and fuel quality, better miles per gallon may be achieved.

Speed Limiter

APR’s ECU upgrade increases the vehicle’s top speed limiter for blistering sprints around the track or across the Autobahn without the speed limiter shutting down the fun.

Left Foot Braking / Brake Boosting:

APR’s Left Foot Braking feature allows more control over the vehicle’s throttle. The factory equipped vehicle’s throttle input is disabled while pressing the accelerator and brake at the same time. Left Foot Braking, a common motorsport driving technique, allows the driver complete control over the vehicle’s throttle and braking system, which may give the vehicle the edge it needs at the track.

Any APR Dealer in the world, connected to the Internet, has direct access to APR’s latest ECU upgrades for loading directly over the vehicle’s OBD-II port. This completely eliminates the need to remove and open the ECU for currently available files and can be uninstalled at any time without a trace!


APR ECU Explorer:
APR’s proprietary ECU Explorer gives APR’s Calibration Engineers unparalleled access to the vehicle’s entire engine management system. Typical commercially available data logging tools, used by most tuners, only allow logging up to 12 engine-operating variables at extremely low data rates. These tools are also limited to a small, specific list of variables. APR’s ECU Explorer is capable of logging every variable found within the ECU with far more variables logged at once, at very high data rates.


APR ECU Composer:
APR’s proprietary ECU Composer is used for altering the engine management system. With full access to every table, map and variable within the ECU, APR’s Calibration Engineers are not limited to a handful of maps as is common for most tuning companies.


APR ECU Assembly:
APR’s Electrical Engineers have the ability to alter the code structure of the ECU. Through code levels changes, APR’s Engineers are able to add features to the ECU. Other changes allow higher torque limits than those achievable through only modifying calibration data or using piggyback devices as is the case for many tuners. This allows APR’s engineers to often not require transmission software to meet or exceed advertised gains. On the highly modified end, this often allows APR to make turbo upgrades operate without the need for external manual controllers.

APR Presents the 1.8T/2.0T EA888 Gen 3 Boost Tap – v2!

The APR Boost Tap for the 1.8T and 2.0T EA888 Gen 3 engines is a simple, yet elegant solution for referencing boost pressure and vacuum as is commonly necessary for boost gauges. The boost tap plugs into an unused port on the factory intake manifold and doesn’t interfere with the factory T-MAP sensor.

 

 

Traditionally boost is tapped by spacing out the factory T-MAP sensor on top of the intake manifold. However, APR’s engineers discovered using this location lead to inconsistencies in intake air temperature readings and potentially a loss of power. Upon this discovery, APR’s engineering team went back to the drawing board and came up with a new and unique solution.

 

Kit Includes:

  • 1 Billet boost tap
  • 2 Viton o-ring seals
  • 1 Stainless steel barbed connection point
  • 1 Brass “No-buzz” mechanical boost gauge restrictor pill
  • 1 Tap cap
  • 5 Stepless OEM style ear clamps
  • 96 Inches of 200 PSI hose
  • 1 T-fitting
  • 5 Black cable ties
  • 1 Bag of anti-sieze
  • 1 Tapping tool

 

Utilizing the included punch tool on a warm engine, a boost and vacuum reference port is easily spread opened on the factory intake manifold. The billet aluminum boost tap then connects to the port and uses dual Viton o-ring seals for leak free operation. The reference hoses connect to the rear of the tap via a barbed stainless steel connection point and conveniently routes through the engine bay.

In addition to the boost tap, APR provides several extra components to help suit each individual’s needs. For those requiring more than one reference source, a T-fitting allows for more tapping points. In the case where a mechanical boost gauge is used, the brass restrictor pill limits flow and cures gauge buzz. Just less than 100 inches of 200 PSI hose is included with OEM style ear clamps and black cable ties to allow for neatly routing hose through the engine bay.

APR Presents the 1.8/2.0T EA888 Gen 3 Cast Downpipe Exhaust System!

 

Upgrading the restrictive factory downpipe with the APR Cast Downpipe Exhaust System is a great way to increase performance and add a sophisticated growl to the exhaust note. Ideal performance is achieved through expelling exhaust gasses at maximum velocity through APR’s proprietary, low-turbulence, investment cast downpipe. Designed and assembled in-house, the system utilizes only premium materials and world-class manufacturing techniques to deliver unmatched quality and reliability.


 

Quick facts:

  • Designed and assembled in-house.
  • T304L stainless steel construction.
  • Argon back-purged TIG welding.
  • Investment cast downpipe.
  • 77mm inlet with integrated flange.
  • Low profile, sealed/corrugated flex section.
  • 76mm outlet with integrated bracket.
  • 8mm billet bracket.
  • 76mm brushed and de-burred piping.
  • Non-swedged/slip-fit/flanged piping.
  • Investment cast o2 bung.
  • 300 cell, 100mm x 100mm GESI catalyst.
  • OEM-style slip-on clamps.
  • Reducer for OEM catback compatibility.
  • APR Stage II ECU Upgrade price waived.
  • Limited lifetime warranty.

The factory downpipe system consists of smaller, 63mm piping with varying bends and multiple restrictive high-cell-count catalysts, all of which contribute to a less than ideal flow path and hindered performance. APR’s engineers took a multi-step approach to maximizing flow, reducing under hood temperature, and eliminating unnecessary restrictions all in a unique package only APR can deliver.

Detailed component photos and information

The APR Cast Downpipe Exhaust System is a complex system designed to deliver maximum performance. Each component was designed and developed with the absolute best in performance, strength, reliability and quality in mind.

Cast Downpipe Inlet and Outlet

The exhaust system features a strong, investment cast, T304L inlet and outlet designed to maximize flow and minimize turbulence. By casting the inlet, APR’s engineers were able to create a smooth and high-flow exhaust path that maximized flow through swept blends and shapes that are otherwise not possible through conventional fabrication techniques. The inlet perfectly matches the factory turbocharger’s 77mm outlet and gradually necks down over a long distance to further enhance performance. The mounting flange and bracket are integrated into the casting, and TIG welding at the flex section ensures a clean inner surface eliminating turbulence, vortices and eddies to the highest degree.

With a nominal wall thickness of 2.55mm the downpipe is strong and produces a refined exhaust note compared to thin wall tubing systems. The cast sections undergo a tumbling process to smooth and de-burr any imperfections inside the pipe, while simultaneously enhancing the exterior finish. Lastly, all necessary surfaces are CNC machined for an accurate fit.

Flex Section

APR’s engineers specified a T304L stainless steel, OEM-style flex section that is fully sealed with a corrugated inner lining to improve flow and reliability. The low profile design and minimal use of bradding material eliminates clearance issues common with other designs that can billow, rub, rattle and fray over time.

Bracket

Designed to stand the test of time, the bracket is CNC machined from 8mm-thick billet T304L stainless steel and the hanger feet are threaded into place, eliminating the need for welds. Weight is removed from the bracket, wherever possible, while not hindering its structural integrity. The bracket attaches to the cast downpipe’s integrated mounting bracket, and CNC machined spacers enable compatibility across multiple vehicles.

Piping

The APR Downpipe Exhaust System features premium grade T304L stainless steel for its excellent appearance, strength and corrosion resistance properties. The pipe is rolled to the 76mm European standard diameter with a 1.5mm wall thickness and a seemingly non-existent weld seam.

Pipe is cut to length in-house via APR’s CNC-controlled bandsaw to an accuracy of .25mm, ensuring a precise fit. Each pipe is de-burred, and the exterior finish is brushed to give the exhaust piping a clean and attractive appearance worthy of the APR name. APR’s fabrication team uses argon back-purging during the welding process, leaving a clean and smooth interior surface, and TIG welding for strength and appearance. Lastly, no swedging or slip-fitting is necessary due to APR’s OEM-style clamp design, leaving smooth and less turbulent connection points.

Clamps

APR’s engineers specified a T304L stainless steel, OEM-style exhaust clamp designed to eliminate the need for flanges, swedging, or slip fittings. By using this low profile design, the exhaust system can be positioned higher in the exhaust tunnel and away from the ground with better clearances compared to flanged setups. Each clamp allows for less turbulence and greater accuracy at the connection points as the pipes simply butt up to one another rather than the ambiguity and voids associated with swedged slip fittings. Furthermore, the clamp doesn’t rely on deforming the pipe to provide a tight seal, making install and removal more convenient.

O2 Sensor Bung

APR’s Engineers paid special attention to the details when designing the APR Cast Downpipe Exhaust System all the way down to the oxygen sensor bung. APR’s O2 bungs are investment cast from T304L stainless steel and are curved to perfectly fit on 76mm piping, without protruding into the pipe, as this would further impede airflow beyond the sensor itself. The bungs are TIG welded to the piping and back-purging is used to ensure the interior surface is smooth and clean.

Catalyst

APR’s engineers specified a high-quality and high-flow GESI metal 300-cell catalyst ideal for forced induction application. During dyno testing, the 100mm x 100mm design showed no measurable loss in power, thanks to the catalyst’s specifications.

Internally the catalytic converter features a proprietary blend of precious metals and loading technology that helps to reduce emissions and smell common on cat-less setups. With performance in mind, the catalyst is placed far away from the turbo outlet to reduce turbulence in the downpipe and to help reduce under-hood temperature. The low-profile catalyst features a fully captured substrate brick, which is furnace braised to the outer mantle and physically captured by the diffuser cones preventing rattling, rotation, and damage to the substrate. Subsequently, a byproduct of running the catalyst is a reduction in noise, making the system as a whole more pleasing to the ear.

Reducer

A simple and removable, T304L stainless steel reducer, featuring a smooth transition, is included, making the APR Cast Downpipe Exhaust System directly compatible with the OEM catback exhaust system.

Oxygen Sensor Harness

A high quality oxygen sensor extension harness is included as the catalyst and sensor bung is relocated further away from the turbocharger.

Furthermore, the clamp doesn’t rely on deforming the pipe to provide a tight seal, making install and removal more convenient.

O2 Sensor Bungs

APR’s Engineers paid special attention to the details when designing the APR Cast Downpipe Exhaust System all the way down to the oxygen sensor bungs. APR’s O2 bungs are investment cast from T304L stainless steel and are curved to perfectly fit on 76mm piping, without protruding into the pipe, as this would further impede airflow beyond the sensor itself. The bungs are TIG welded to the piping and back-purging is used to ensure the interior surface is smooth and clean. Lastly, a billet T304L stainless steel bung plug is included to cap off extra ports not needed on some models.

Catalyst

APR’s engineers specified a high-quality and high-flow GESI metal 300-cell catalyst ideal for forced induction application. During dyno testing, the 100mm x 100mm design showed no measurable loss in power, thanks to the catalyst’s specifications.

Internally the catalytic converter features a proprietary blend of precious metals and loading technology that helps to reduce emissions and smell common on cat-less setups. With performance in mind, the catalyst is placed far away from the turbo outlet to reduce turbulence in the downpipe and to help reduce under-hood temperature. The low-profile catalyst features a fully captured substrate brick, which is furnace braised to the outer mantle and physically captured by the diffuser cones preventing rattling, rotation, and damage to the substrate. Subsequently, a byproduct of running the catalyst is a reduction in noise, making the system as a whole more pleasing to the ear.

Reducer

A simple and removable, T304L stainless steel reducer, featuring a smooth transition, is included, making the APR Cast Downpipe Exhaust System directly compatible with the OEM catback exhaust system.

The APR Difference:

The Engineering and Designing Phase

In the past APR worked with other manufacturers to develop a limited range of private-label exhaust systems outside the scope of APR’s internal development and manufacturing capabilities. Understanding the limits of such a program, combined with APR’s desire to deliver higher-quality products in a timely manner with better customer support, APR invested in internalizing the program. With the release of this exhaust system and the others like it, APR is pleased to present our first systems fully designed and engineered in-house from the ground up!

Design and development begins with the use of APR’s professional grade in-house coordinate measuring machines. APR’s engineers have full access to a Romer Absolute arm with integrated laser scanner, FaroArm and Creaform 3D laser scanner for collection of special constraints surrounding the factory exhaust system. The engineers scan the vehicles and create detailed 3D maps of their design environment while designing each system in PTC Creo 3.0 CAD software.

Using APR’s in-house stereolithography 3D printer, rapid prototypes are created for fitment on the vehicle. The design is easily and quickly verified, and if necessary, changes can be made. Once adequate clearances and fitment is confirmed, especially in areas that move under load, physical quick-cast prototypes are created and fitted for final verification through real-world use.

APR’s world-class manufacturing partners from around the globe are responsible for manufacturing each component that falls outside of APR’s internal capabilities. Working closely with each manufacturer, APR’s engineers supply CAD models, materials specs, and other design specifications and work hand-in-hand with the manufacturer to develop the components. The end result is a collection of components, wholly unique to the APR name, awaiting final finishing, assembly and quality control at APR’s 78,000 square foot facility in Opelika, Alabama in the USA.

The Fabrication, Finishing and Assembly Phase

Manufacturing takes place both internally and externally to APR while finishing and assembly is completed in-house. APR’s fabrication team cuts, brushes and de-burrs premium grade T304L stainless steel piping for use in each midpipe. Then each cast component is sent through the ceramic vibrating tumblers to smooth and de-burr surface imperfections. Each component is then cleaned by hand and prepared for assembly.

APR’s fabrication experts TIG weld each component, creating reliable, high quality and attractive welds. Each component is back-purged with argon during the process ensuring the weld is strong and consistent, as well as clean throughout. With this process complete, the APR Cast Downpipe Exhaust System is born!

Final Quality Control

APR has placed a large emphasis on improving quality control across various product lines, and the exhaust program is not excluded. To ensure the systems are delivered as advertised, APR’s engineers have taken a multi-step approach that encompasses many techniques that go beyond the industry standard.

Metallurgy Testing

APR’s engineers request full metallurgy reports with each batch of components to ensure the components are made with the T304L stainless steel grades specified on the original design prints. This information is then cross-referenced against randomly selected and independently tested samples before the components are released for assembly.

Dimensional Inspection

Great designs only matter if the manufacturer delivers the components as expected. To help ensure the designs are as specified, APR’s engineers randomly select components and conduct full dimensional inspections using in-house 3D laser scanning equipment. Tolerances are digitally checked against the original specifications and passed or failed based on the results.

Fixtures

Operating in an environment designed for accuracy and repeatability, APR’s fabrication experts leave little room for error during the final assembly phase. Jigs and fixtures, created in-house, live on custom-specified fabrication tables featuring repeatable indexing holes and extremely flat surfaces. This working environment ensures the highest level of quality control during the assembly process and safeguards against dimensional variations potentially created during the manufacturing process. The end result is a system that fits every time as it’s true to the original design specifications.
Visual Quality

When hand-building the products in-house, an extra level of control takes place. Components are visually checked for imperfections, and items that fall out of quality standards are rejected. The products are then packaged with care before being distributed across the world.

APR’s confidence in the system’s quality allows for a limited lifetime warranty.
