Smooth bends, tight packaging, and two attitudes. The SwitchPath* Exhaust is comprised of handcrafted 3-inch and 2.5-inch U.S.-sourced T304L stainless steel single pass, 5-cylinder-specific tuned driver*s side muffler with a valved passenger-side tip outlet. SwitchPath* retains the factory valve behavior and obeys the ECU's commands based on throttle input, engine speed, Drive Select, and the factory-issued exhaust button within the cabin. Sneaking out in the morning or creeping through town? Close the valve. Drop the hammer (or click into Dynamic mode), and your RS3 will sing a signature AWE tune with enhanced RS burbles that will provoke a firm grin. Have SwitchPath* and want to go Track Edition? No problem, we have a Conversion Kit for that! AWE SwitchPath* for the 8V comes standard with Diamond Black 180mm RS-style oval tips, complete with stamped AWE logo.
