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.

STE PPD Demonstration in my Stage III B5 S4
Video demonstration of the Performance Parameters Display (PPD) by Supreme Technology & Engineering (STE)... displaying the many functions and on-board displays introduced with the installation of this module. Please note... in several instances in the video I refer to the module as 'the STE'. This is a mistake, and should be replaced with 'PPD', as the PPD is the module, while the STE is the company who makes it. (Audizine: PovGRide742)





Audi B5 S4 SSAC/XS Power "Twin 1" Catback Exhaust
Car is completely stock other than mild APR stage 1 tune (15 PSI peak) and the SSAC/XS "Twin 1" Power catback. This means the car has stock downpipes and mid pipes. Review: Exhaust came very well packaged and fit excellent. Shipping was also very fast! The car sounds great. The video does not fully capture the sound. It sounds incredibly deep and refined compared to stock. The system is truly a night and day difference. The Exhaust also looks much better than stock with the three inch tips. I highly recommend the Exhaust to anyone with a B5 S4!!
