A recent post made by Arin@APR shows some incredible gains to be had with the B8-chassis Audi A4 when upgrading to “APR Stage 2″ using their new RSC free-flow exhaust system.  Still in development, but available to the public VERY soon…

Several days back APR showed the world a teaser of the new APR Performance RSC Turboback Exhaust Systems in both Dual Exit and Single Exit Configurations.

The APR RSC Turboback Exhaust Systems were so free flowing the Engineers were able to make safe calibration changes which resulted in the following:

1. Significantly reduced turbocharger spool time over both stock software and APR stage 1 software.
On the days of testing, stage 1 torque levels at 2400 RPM’s were met and exceded at 2000 RPM’s (400 RPM’s Sooner!) simply by running APR stage 2 software with the RSC Turboback Exhaust System

2. Significantly increased and broadened the torque curve compared to both stock and APR stage 1 software.
-On the days of testing, stage 2 torque levels rose 89 FT-LBS under the curve compared to stock software. Peak torque rose from 267 ft-lbs to 355 ft-lbs, for a 88 FT-LBS peak increase.
-On the days of testing, stage 2 torque levels rose 66 FT-LBS under the curve compared to stage 1 software. Peak torque rose from 334 ft-lbs to 355 ft-lbs, for a 21 FT-LBS peak increase.

3. Significantly increased horsepower, especially the area under the curve compared to both stock and APR stage 1 software.
-On the days of testing, stage 2 torque levels rose 50 HP under the curve compared to stock software. Peak power rose from 212 hp to 248 hp, for a 36 hp peak increase.
-On the days of testing, stage 2 torque levels rose 27 HP under the curve compared to stage 1 software. Peak power rose from 235 hp to 248 hp, for a 13 hp peak increase.

All of our data was collected on back to back runs and are the results of average data. Data was also collected on the same car during several days of testing. Gains between runs were in some cases higher but we have chosen to show you an average of what you’ll expect to see as data can change between runs based on countless variables.

Now for the dyno charts of our development progress!

We are pleased to announce APR’s release of their Audi B8 S4 3.0 TFSI RSC Performance Exhaust System! This is the first RSC™ Exhaust System for the Audi marque in the new 3.0T B8 S4 Model Years 2010+.

Reflective Sound Cancellation allows for maximum exhaust gas flow while completely eliminating in cabin sound resonance (drone). RSC™ incorporates innovative technologies developed in conjunction with NASA. With limited use of packing materials and no baffles, RSC™ allows for a completely straight and free flowing exhaust path through the RSC™ mufflers. Reflective Cancellation bounces the undesirable sound waves into each other to attenuate the wave and completely eliminate the low frequency tones that create drone. Each RSC™ muffler is tuned to eliminate specific, undesirable sound frequencies allowing only the engine’s desirable exhaust notes to be heard and improving performance.

APR’s RSC™ Performance Exhaust for the B8 S4 introduces modular tip design that allows the end user to specify an initial tip color of either Stainless Steel or Diamond Black and other tips can be ordered separately and changed at the owner’s pleasure. Be on the lookout for special edition, limited run tip options in the future to make your S4 even more exclusive and individual to your tastes. Installation and removal of exhaust tips can be accomplished easily with only basic hand tools.

Normally Aspirated engines and Supercharged engines still rely on proper exhaust tuning to promote the optimal flow velocity of exhaust gasses leaving the exhaust ports. APR introduces a unique and proprietary X-pipe design that was developed through multiple reiterations to perfectly match the pulse of each cylinder in the 3.0T to provide optimal exhaust flow. Often times, exhaust manufacturers will incorporate X-pipes into all Normally Aspirated or Supercharged applications generically without realizing that the sizing and shape of the ports in the X-pipe require specific tuning to each engine application. APR’s Engineering Team has discovered a trade secret exclusive to APR’s RSC™ Exhaust System that promotes maximum velocity of exhaust gasses by way of the X-pipe to ensure your APR RSC™ Exhaust System will compliment your future modification choices at even the highest horsepower and torque possible.

We are doing our best to get these exhausts in as quickly as possible and look forward to our first installation! The APR B8 S4 RSC Exhaust has already been added to our website so you are welcome to pre-order the exhaust online to guarantee you get the first that arrives or call us at 425.895.0000.

We’re still going to be at the end of 91st off of Willows Road here in Redmond but we will be in a larger facility to better accommodate our very large inventory – 50% larger than our current location. The showroom will also be larger than our current one which will allow us to better display our products. It’s going to be a long, slow process to move into our new building and we’re going to need your help! So… as with any move, we present to you:

Just about any item we have on the shelf ready for pick-up or shipping will be quoted with sale pricing (if not already on sale) to help minimize the number of items we need to move into our new facility. If an item online at achtuning.com is not on sale and we have it on the shelf, contact us directly for a quote and take advantage of big savings!!
