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.
Audi S4 biturbo quattro AWD - Best of oversteer, drifts, and hoonage driving sideways...
A mash up of some of my favorite sideways driving in my VAST tuned Stage III B5 Audi S4. Unfortunately some of my best work isn't on camera, so this will have to do! Audio track is "Guidebook of the Halos.mp3" from Dan-O. (licensed for free use under creative commons) http://www.danosongs.com/

All of this was done on a completely STOCK motor! Check it out!
