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.

Listed in the APR exhaust applications below, exhuasts marked with RSC™ contain the Reflective Sound Cancellation silencer sections. Where exhuasts are listed as 'Stealth' this means that they contain convential silencers. We can supply the more noisy Sport version of the APR exhaust on request please contact JKM.
