Description
Overview
The BMW (3.0) Exhaust System Kit from AWE Tuning is the first AWE SwitchPath™ configuration for BMW to incorporate patented drone-canceling 180 Technology®. Engineered as a complete cat back exhaust system for the S58 engine, it blends push-button attitude with refined, full-bodied sound — delivering no drone, minimal bends, and maximum flow. If you’re ready to shop for exhaust hardware that transforms how your BMW sounds and breathes, this valved SwitchPath™ system is built to impress.
Constructed from 3-inch U.S.-sourced T304L stainless steel, this performance exhaust begins after the factory mid pipe. A precision X-pipe immediately smooths the S58 of its rasp, deepening the tone before it’s refined further by the bespoke SwitchPath™ muffler in the rear. The result is a car exhaust that behaves exactly how you want it, whenever you want it.
Sound On Demand
With the valves 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 stay close to stock with no drone thanks to 180 Technology®. Drop the hammer with the valves closed and SwitchPath™ sings a proper M anthem; open the valves and the S58’s roar is uncorked. This SwitchPath™ tech also responds perfectly to the many transmission settings and shift points in automatic vehicles.

Configuration & Tips
This cat back exhaust system is finished with four Diamond Black tips at 4.5 inches, giving your BMW a purposeful, aggressive rear-end presence that complements the deep, refined tone. The valved SwitchPath™ muffler is tuned specifically for the S58, so every note is intentional. Choose the setup that matches your driving style — dial it back for a composed daily driver, or open the valves for full-throttle theater.
