AWE's 3.0T Touring Edition exhaust for the B8.5 S4 delivers refined idle civility and a pronounced full-throttle wail. Handcrafted T304L construction and AWE 180 Technology® tune the tone while avoiding drone. The system produces about 8 hp and 9 lb-ft of torque to the crank, fits directly as a bolt-on, and ships with 102mm chrome silver tips. Note: 102mm tips are specific to 2013+ S4 applications and the rear section is re-engineered to accommodate them.
