AWE B8 S4 Exhaust
This video was designed to capture the before and after audio as a result of upgrading to the resonated, full Exhaust system offered from AWE tuning. For those who dont want to hear the stock sounds and want to go right to the glorious sounds of the AWE Exhaust, skip ahead to 1:42 in the video. Hopefully this video helps offer some real world driving scenarios to get a better understanding of how this Exhaust might sound on your car. This Exhaust is very civil when cruising around town and doesn't drone. But when it's time to go wide open throttle, it exudes some rather prodigious, delightful sounds. This Exhaust system is the resonated version and includes the downpipes offered by AWE. The vehicle in this video is equipped with the S-tronic transmission and factory intake system. For those looking for an even louder setup, AWE also offers a non resonated version of this Exhaust.

STaSIS 2010 S4 Exhaust Testing
STaSIS stopped by the shop yesterday to show off their spanking new 2010 S4 Exhaust. It was the exact same car featured in this video. This is the "Touring" version of the Exhaust (low RPM resonators) and it sounded just right (not too loud). Check out for yourself. You can always upgrade to the "Challenge" sound via a $100 kit if this is too quiet for you. http://www.europaparts.com/stasis-touring-Exhaust-s4-b8-low-rpm-resonators.html

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.
