Introducing the first AWE Exhaust for the Audi S3 to ever feature patented drone-canceling 180 Technology®. The Touring Edition features a 3” inlet complete with an adapter to accommodate the factory downpipe perfectly while leaving an open 3” connection. In the rear resides AWE’s patented 180 Technology® resonators responsible for maintaining straight-through performance while decimating drone-prone frequencies. Thanks to the design and construction of 180 Technology® resonators, the internals will not break down and degrade over time causing tone change. Just full-bodied, drone-free rumble for life from the point of installation. This configuration provides the best ratio of interior refinement and exterior rumble on the market. No valves needed. Switch driving modes and the exhaust will render the same result as a vavled exhaust. It's the do-it-all exhaust for every day drivers. Comes complete with quad 4.5" slash-cut, double-walled tips in diamond black. The AWE Touring Edition for the 8Y S3 is made in the USA and backed by AWE’s Fitment Guarantee, 50 state emissions compliance, No Check Engine Light Guarantee, and the AWE Lifetime Warranty.
