Our good friends at APR have announced the APR B5 S4 RSC Exhaust System is coming soon! Straight through exhaust without drone. Perfect for those pushing the limits of the 2.7T.
We are hoping to get our hands on one for our Project B5 S4.
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.
The B5 S4 in the video has a full APR RSC Exhaust System with an APR Stage III K04 Turbocharger System.
