Description
Overview
The AWE Tuning Audi (4.0) Exhaust System Kit is a purpose-built catback exhaust engineered specifically for the 4.0TT platform. Constructed from 3-inch U.S.-sourced T304L stainless steel, this SwitchPath™ Edition exhaust system pairs premium materials with intelligent valve control so you can command your car’s personality on demand. It’s a true cat-back configuration, meaning it replaces the exhaust pipe and components from the catalytic converters rearward for a comprehensive upgrade to your car exhaust.
Key Benefits
At the heart of this performance exhaust is AWE’s proprietary 180 Technology® drone-canceling resonator, tuned specifically for the 4.0TT. This bespoke, straight-through center resonator keeps drone-prone frequencies in check while still letting the exhaust note breathe. The result is an exhaust system that stays civil when you want it and roars when you don’t.
Because SwitchPath™ technology maintains and utilizes the factory valve behavior, the exhaust obeys orders given through the MMI and Drive Select — exactly as the stock exhaust would. With the valves closed, the SwitchPath™ Exhaust produces a sophisticated soundtrack, and at cruising speeds the interior acoustics stay close to stock with no drone thanks to the 180 Technology® resonator. Drop the hammer while cruising and it responds perfectly, behaving just like factory. Open the valves and the 4.0TT’s roar is fully uncorked — Dynamic mode delivers the ultimate contrast, with an exhaust note that is powerful, clean, and aggressive.
