APR B5 S4 RSC Exhaust System
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.
