Description

Unified design for OPF euro and non-euro spec cars, 50-state legal Cat Back design, precision-engineered X-pipe to unlock a clean S55 tone, retained M-Sport button functionality, 3″ CNC mandrel-bent configuration, max gains of 12 hp and 16 lb-ft of torque at the wheels and signature AWE 102mm double-walled, slash-cut tips in Chrome Silver or Diamond Black. Throw in a No Check Engine Light Guarantee, Perfect Fitment Guarantee and Lifetime Warranty and you’ve got the only real option for your S55. Minimal bends, maximum flow, and push-button attitude. The SwitchPath Exhaust is a true Cat Back configuration comprised of 3-inch and 2.5-inch U.S.-sourced T304L stainless steel, a precision x-pipe, and a valved SwitchPath muffler tuned specifically for the S55. Beginning after the secondary catalysts, the precision X-pipe immediately helps smooth the S55 of its infamous rasp, allowing the tone to be further refined by the bespoke muffler in the rear. The closed valve experience: When the valves are closed, the SwitchPath Exhaust produces a refined, aggressive howl while remaining full-bodied and powerful ? no congested, metallic sounds here when on the throttle. At cruising speeds, interior acoustics are close to stock. AWE SwitchPath tech also responds perfectly to the many transmission settings and shift points in DCT vehicles.
