APR Audi B5 S4 2.7T RSC™ Performance Exhaust System

APR's RSC™ technology is now available in the 2.7T RSC™ Performance 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 Sound 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 design specifications and manufacturing requirements result in a Twin 2.5" to 3" mandrel bend stainless steel performance exhaust system unmatched by any other. RSC™ technology ensures the maximum possible performance increases from any performance exhaust system while maintaining refined and unobtrusive sound inside the cabin.

APR's RSC™ catback exhaust system has the same flow capabilities as a large straight pipe exhaust system flow tested and certified capable of supporting 1100BHP. APR's new RSC™ catback exhaust system is the perfect solution for those of you with 500+ AWHP that want quiet, unobtrusive cabin sound levels but a mean growl at wide open throttle.
