AWE SwitchPath™ Catback Exhaust for BMW F8X M3/M4 - Diamond Black - 3025-43074
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.
