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. RSC™ or Reflective Sound Cancellation allows for maximum exhaust gas flow while completely eliminating unwanted in cabin sound resonance known as "drone". Reflective Cancellation bounces the undesirable sound waves into each other to attenuate the wave and eliminate the low frequency tones that create drone. Each RSC™ muffler is tuned to eliminate specific, undesirable sound frequencies allowing only the engine's true and desirable exhaust note to be heard and improving performance.
