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.

Benefits of the new technology allow APR’s RSC™ Exhaust Systems to meet the European Union and other countries’ noise requirements of 90db or less in new car exhaust sound and even increase performance over traditional performance exhaust systems.

Many of the competing exhaust systems do not significantly reduce the low frequency tones that occur around 50 to 200 Hz, which makes the tone levels closer to running without a muffler (red bar).It’s these frequency tones that are responsible for“drone”. RSC acoustic prediction methods and design techniques reduce these tones without compromising the sporty sound we all enjoy from high performance automobiles.

RSC™ technology provides sound levels comparable or even quieter than OEM exhaust systems at cruising speed.RSC’s™ straight through design minimizes back pressure and provides gains greater than other performance exhaust systems. The example shown for the Volkswagen GTI demonstrates the ability to tailor the sound spectra to eliminate drone while maintaining a sporty sound, especially under full throttle.
