Audi S4 Performance Exhaust - AWE Tuning - Cat-Back SwitchPath - Silver - `17-`27. A valved cat-back that gives your S4 on-demand volume control and a crisp, refined AWE tone.

Designed for the B9 S4, SwitchPath™ pairs non-resonated downpipes, a precision x-pipe, and dual valved mufflers you can control via the optional SwitchPath™ Remote or factory valves. Fabricated from dual 2.5" CNC mandrel-bent .065" wall T304L stainless, it delivers AWE’s signature sound. 102mm double-walled Chrome Silver tips wear the AWE logo and adjust individually. Max gains of 16 hp and 17 lb-ft at the crank (exhaust). Note: brief valve rattle on cold start may occur and fades quickly.
