Description
Overview
The AWE Tuning BMW (Convertible/Coupe/Sedan – 3.0) Exhaust System Kit is a true Cat Back performance exhaust engineered specifically for the S55-powered BMW F8X M3 and M4. Representing the second generation of AWE’s SwitchPath™ technology, this valved exhaust system was designed to make the S55 sound epic with the valves closed — and even more so with them open — all while remaining emissions compliant. Minimal bends, maximum flow, and push-button attitude define this borla-alternative caliber catback exhaust built to elevate your car exhaust experience.
Precision Engineering & Materials
Constructed from U.S.-sourced T304L stainless steel, the system combines 3-inch and 2.5-inch tubing with 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. Every exhaust pipe section is crafted to deliver a clean, congestion-free flow path so the engine breathes freely at every point in the rev range.
Sound Character
When the valves are closed, the SwitchPath™ Exhaust produces a refined, aggressive howl while remaining full-bodied and powerful — no congested, metallic sounds when on the throttle. At cruising speeds, interior acoustics are close to stock, making this a livable daily companion that transforms into a proper M anthem the moment you drop the hammer. AWE’s SwitchPath™ tech also responds perfectly to the many transmission settings and shift points in DCT vehicles, giving you push-button command over your exhaust character.
