***The versions***

The SwitchPath™ Exhaust

AWE Tuning SwitchPath™ Exhaust Technology is a proprietary solution that utilizes valves in the exhaust to control tone and volume. Controlled by a combination of throttle input and engine speed, SwitchPath™ Technology keeps the S3 quiet and comfortable while cruising, but give it the boot and you’ll unlock an aggressive and exotic exhaust note.

The Track Edition Exhaust

The lower priced sibling, the Track Edition Exhaust is crafted of the same quality T304 stainless, made in house, and delivers the same power gains as the SwitchPath™ Exhaust. The difference comes in the removal of AWE Tuning’s valving system. In other words, this system is the “open valves” side of the spectrum, all the time, and will be most pronounced in the mid range.

Performance Downpipes


To further hone the tone and performance of your S3, we’re offering both resonated and non-resonated downpipes as well. Both versions feature our No Check Engine Light Guarantee, Fitment Guarantee, a unique flex-pipe section to isolate engine movement, and offer our Lifetime Warranty on the downpipe (one year on the catalyst).
Resonated Downpipe: Slightly louder than the stock S3 downpipe. Featuring our No CEL Guarantee (even without software) and a sophisticated and distinguished tone.
Non-Resonated: Removes the resonator for a more aggressive note, much louder than the stock downpipe. Featuring our No CEL Guarantee (even without software) and a pronounced note.

Both the SwitchPath™ Exhaust and the Track Edition Exhaust are available with downpipes as a package for savings. Not sure if you want the downpipes yet? No worries. You have one year from the purchase date of your exhaust to add downpipes at the package price.

APR Presents the TT / TT-S Cast Downpipe Exhaust System

Posted on June 2, 2015 – 9:00 am

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.
  • 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 all in a unique package.

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 maximized 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 DL501 S Tronic TCU Upgrade for the B8 / B8.5 S4 & S5!

Posted on May 14, 2015 – 9:38 am

APR is pleased to present the ultimate transmission control unit (TCU) upgrade for the DL501 Gen 1, Gen 1.5 and Gen 2 S Tronic transmissions! APR’s TCU upgrade is available for 3.0 TFSI platform vehicles and is conveniently flashed to the vehicle’s TCU through the OBD-II port with user definable options selectable at the time of install.

APR’s TCU upgrade goes beyond the overly simplistic norm of raising a few limiters, and offers a wide gamut of changes designed to completely enhance the driving experience. With an in-depth knowledge of the transmission’s inner workings and control strategies, APR’s engineers have improved many aspects of the transmission from accelerative performance to daily drivability, while also incorporating new features including several typically reserved for higher-end Audi Quattro GmbH RS models.

Depending on the driving scenario, APR’s calibration experts have created multiple operating modes designed to deliver ideal performance for the given driving condition. When using launch control, the transmission enters a maximum acceleration mode designed to provide the fastest possible acceleration through a heightened application of torque, optimized shift points and shift strategies among other performance related enhancements. Under blistering, near wide-open throttle, the transmission enters a different state of performance with shift maps optimized for power delivery on vehicles with modified engine software. Manual and Tiptronic mode are tailored to the driver’s desired auto up/down shift preferences at the time of install include several features to enable quicker paddle response times and faster upshifts on Gen 2/B8.5 models. Finally under part-throttle daily-driving in both Drive and Sport mode, the transmission remains calm and smooth. Common clunks and driver annoyances are addressed and the transmission comfortably responds to the driver’s input without constantly and aggressively seeking the highest gear possible.

Feature List

  • 7,200 max shift point with gear dependent overshoot protection.
  • User adjustable 3-Step multiple launch control RPM.
  • User definable* max launch control RPM up to 6,000 RPM.
  • User definable* manual mode downshifts (on/off).
  • User definable* manual mode upshifts (on/off).
  • Launch control enabled on all models.
  • Launch control response enhanced for quicker launches.
  • Launch control limits raised from 200 to 3000 launches.
  • Launch control Max acceleration mode enabled for the fastest possible acceleration.
  • Multiple acceleration modes defined for various driving scenarios.
  • Manual mode / TT mode paddle response time optimized.
  • Manual mode / TT mode shift optimized with gear dependent thresholds on Gen 2/B8.5 Models.
  • Torque intervention limits raised, while retaining temperature protection.
  • Temperature management modified.
  • Transmission coolant pump optimized during high temp scenarios.
  • Gear display enabled in Drive and Sport.
  • Optimized Drive and Sport mode shift maps.
  • Downshift “lockout” disabled below previous gear’s max RPM.
  • First gear, rolling-stop, “clunk” addressed.
  • First gear “short shift” addressed.
  • Significant power increase on applications meeting peak power well above the vehicle’s factory defined shift points.

*APR’s DirectPort Programming suite allows the end user to tailor the TCU upgrade to their needs at the time of installation.

Drive (eco) and Sport Mode:

APR’s engineers have paid close attention to the factory shift maps in drive (eco) and sport mode to help ensure a more pleasurable driving experience. In each mode under high-torque and high-rpm situations, the shift points are increased progressively just below the transmissions new maximum shift point of 7,200 RPM. Gear dependent overshoot protection prevents the transmission from hitting the rev limiter prematurely. Finally using launch control enables the maximum acceleration mode while in Sport.

Under low-torque, low-rpm part-throttle situations, both drive mode and sport mode behave similar to stock. The shift points are raised to prevent the transmission from over aggressively seeking seventh gear prematurely in drive mode and to provide a more sporty feeling in sport mode. The first to second gear short shift has been addressed and while rolling to a stop, the transmission will no longer prematurely downshift to first gear, resulting in a clunky transition.

Manual and Tiptronic Modes

APR’s user definable options allow the end user to configure how manual mode operates. The kick-down switch, which is responsible for an automatic downshift in manual mode, is enabled by default but can be disabled at the time of install. Likewise, the auto upshift that occurs near the new 7,200 RPM redline can also be disabled if the end user chooses, allowing the engine to bounce off the limiter like a manual transmission. For safety’s sake, the first to second auto upshift is always enabled. The transmission does not lock out any manual downshifts so long as the shifting does not result in an engine RPM above the max shift point. In all situations, paddle delay is greatly reduced allowing for more responsive shifts to take place. On Gen 2/B8.5 models, using the paddles and shifter, above gear dependent comfort thresholds near 3000 RPM, will result in lightning fast gear changes as the transmission enters a new “quick shift” upshift mode. Lastly Tiptronic mode is a temporary manual mode accessible in drive (eco) and sport modes by pressing the paddles on the steering wheel. While in this temporary mode, auto upshift and kick down switch are enabled.

Launch Control

APR’s 3-Step launch control is unlike anything else in the market. At the time of flashing, the user chooses a maximum launching RPM up to 6,000 RPM. When activating launch control, up to three launching RPM’s are available, allowing the end user to choose the best launching RPM based on the current conditions!

At 100% throttle with the kick-down switch engaged, the vehicle will select the highest launching RPM. At 100% throttle with the kick-down switch not engaged, a lower launching RPM is activated. Finally, at roughly 50% throttle the transmission chooses the lowest launching RPM. When properly dialed in, the user is left with incrementally higher launch points ideal for the street, track and sticky tires.

Utilization of launch control results in the transmission entering the maximum acceleration mode. During this mode, intervention between a shift is minimized, resulting in faster acceleration that keeps the driver planted to the back of his or her seat. Furthermore, the transmission’s coolant pump is fully optimized to keep oil temperature within the desired operating temperature.

Launch control is activated on all models, including those without it from the factory. The conditions necessary to enable launch control have been tweaked to make activation easier and the delay typically present after lifting the brake and beginning of the physical launch has been greatly reduced. Lastly the factory 200 launch limit has been raised 1400% to 3000 launches!

Recommendation: When using launch control, excessive wheel spin will not improve acceleration and may cause undesirable behavior. APR suggests using lower launch limits near 4,000 RPM under low grip situations. Maximum launch RPM is only ideal with drag slicks / radials on a well-prepped drag strip.

S Tronic Temperature Management

Temperature management is an important part of the DL501 transmission. While some may simply remove temperature protection routines all together, or mistakenly raise temperature protection torque limiters sky high and claim increased cooling performance due to zero transmission intervention, APR’s TCU upgrade only allows the maximum safe temperature levels before intervention. Under high stress scenarios, such as launch control, the transmission’s cooling pump runs at maximum speed until the desired transmission temperature is achieved.

Unlike the factory intervention routine, which allows for nearly no torque to be transmitted through the transmission at all after limits are crossed, APR’s over temp intervention allows for a limited amount of torque, enough so the vehicle can be safely driven off the track or pulled to the side of the road during intervention. In keeping the vehicle moving, airflow continues across the radiators, which in turn keeps coolant temps low and aids in removing heat from the factory DL501 oil coolers to restore full operation.

Torque Limits

Various factory torque intervention limiters are raised to their maximum value to eliminate unintended torque intervention, across the rev range, during normal and spirited driving. However, important and critical limiters are kept in place or only slightly modified, such as those related to temperature protection, to prevent premature damage to the transmission in dangerous scenarios.

Gear Display Indicator

In drive (eco) and sport mode, the vehicle’s multi function display will now indicate the currently selected gear rather than a generic D or S.

Acceleration Improvements

APR’s engineers were able to improve vehicle acceleration through enhancements such as better launch control, higher shift points, and measurable reductions in shift duration and shift intervention as illustrated above.

The graph above shows longitudinal acceleration G-Forces, and the below graph shows vehicle speed over time on an APR Stage II B8 S4 with race fuel. APR’s TCU upgrade provided stronger acceleration after the launch which carries to a higher redline shift point. During the shift, very little intervention took place, keeping G’s high and the driver planted in the seat during the quicker shift. Stock, however, suffered more losses, longer shift durations, and even more extreme losses and durations during the common “short shift” issue. Vehicle speed was greatly affected as is evident by the noticeable deviation in acceleration at 40 MPH on the graph below.

The APR TCU equipped vehicle continued to gain in speed over the stock setup thanks to higher shift points, quicker shifts, and less torque intervention as illustrated in the graphs. 0-120 MPH was reduced by .75 second over the stock TCU and .97 seconds over the stock TCU exhibiting the “short shift” issue!

Reported figures measured using a P-Box on a US Spec 2012 B8 S4 with an APR Pulley, APR CPS, APR Exhaust, APR Intake, APR Stage II software and race fuel. Results will vary depending upon location, environmental conditions, vehicle, transmission, vehicle health, operating conditions, temperatures, fuel grade, tires, suspension setup, other variables and other modifications.

Increased Power

On some models, the transmission’s maximum RPM is set to as low as 6,400 RPM, which is well below the max engine speed as defined by the ECU upgrade. In doing so the engine is unable to produce peak power, as it typically occurs at the engine’s max RPM. Through increasing the max shift point, peak power grows further and results in an additional 20-30 horsepower depending on model, stage and octane as illustrated below.

Reported wheel figures measured using APR’s in house Dynapack Dynamometer with a US Spec 2014 B8.5 S4 in AWD mode with an APR Pulley and APR Stage II software, using SAEJ1349 correction and an average of multiple runs. Crank figures are estimated based on the measured wheel figures. Results may vary depending upon environmental conditions, vehicle, transmission, vehicle health, operating conditions, temperatures, fuel grade, dyno type, dyno setup, other variables and other modifications.

The APR Difference:

APR DirectPort Programming:

APR’s DirectPort Programming is now available for the Temic Tricore DL501 Gen 1, Gen 1.5 and Gen 2 transmissions. Any APR Dealer in the world, connected to the Internet, has direct access to APR’s latest TCU upgrades for installation directly over the vehicle’s OBD-II port. This completely eliminates the need to remove and open the TCU and can be uninstalled at any time!

APR TCU Upgrade Creation:

APR’s engineers have taken a direct and custom approach to calibrating the TCU. All too often others create a generic calibration that is forced across a wide range of different vehicles and transmission versions. Unfortunately this generic method of copy and paste tuning can result in some undesirable effects, such as slow up shifts and downshifts, torque interventions, stumbling, immobility and general incompatibility. In some extreme cases, damage to the transmission can occur. With many factory TCU variations available for the transmission, APR’s engineers have painstakingly ensured every TCU upgrade is created using the transmission’s original file to ensure the ultimate experience!

APR TCU Composer:

APR’s proprietary TCU Composer is used for altering the transmission management system. With full access to every table, map and variable within every TCU, APR’s Calibration Engineers are not limited to the handful of pre-defined maps.

APR TCU Assembly:

APR’s Electrical Engineers have the ability to alter the code structure of the TCU. Through code-level changes, APR’s Engineers are able to add future features to the TCU otherwise impossible through calibration changes alone.

Application Guides

For use with APR’s ECU upgrades, the latest version is REQUIRED. This update MUST be checked and installed at the time of install.
