The AWE SwitchPath Exhaust is a valved cat-back system for the Audi S3, handcrafted from CNC mandrel-bent 3-inch and 2.5-inch U.S.-sourced .065-inch wall T304L stainless steel. A valved passenger-side outlet retains the factory valve behavior and obeys the S3's ECU commands based on throttle input, engine speed, and Drive Select, so it stays quiet around town and opens into a signature AWE tune with enhanced crackle in Dynamic. It exits through 102mm double-walled, slash-cut tips with a stamped AWE logo and delivers max gains of 12 hp and 9 lb-ft of torque at the wheels. Installation is a direct bolt-on, and the system can later be converted between SwitchPath and Track Edition.
