AWE Tuning Audi B8 2.0T Resonated Performance Downpipe for A4 / A5For the enthusiast interested in a more aggressive sound, we offer the AWE Resonated Performance (50 state legal) Downpipe. By replacing the large stock resonator with a more compact but still straight through unit, we were able to increase sound volume while adding a slightly deeper tone. The AWE Resonated Performance Downpipe will mate to the AWE exhaust system, or any other exhaust designed to work with the stock downpipe. This Part Fits: Year Make
