APR Audi B8 S4 3.0T FSI RSC Performance Full Catback Exhaust System

APR is pleased to present our first RSC™ Exhaust System for the Audi marque in the new 3.0T B8 S4 Model Years 2010+. 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 OEM Exhaust system consists of Headers, Catalytic Converters, Resonated Downpipes, a Center Resonator, Rear Mufflers and Exhaust Tips. The APR RSC™ Performance Exhaust System is a Full Catback Exhaust System as it replaces the OEM Resonated Downpipes, Center Resonator, Rear Mufflers and Exhaust Tips. On stock software the Exhaust saw gains of up to 18 HP.

APR Sound tests for the B8 A4 2.0 TFSI Exhaust systems. The vehicle in this video is a 2010 B8 A4 2.0 TFSI. It's a tiptronic and has quattro.

APR Also offers both systems in a true, ful, turboback Exhaust system complete with high flow catalytic converter and resonated downpipe. More videos of these systems to follow!
