We made the S63 sound epic with the valves closed, and with them open… again! All while remaining emissions-compliant.
In axle-back form, the SwitchPath® retains the M5’s factory mid-section, coming in right at the rear axle. The AWE Switchpath® Axleback Exhaust maintains a 3” diameter, shaves weight from the rear, and retains the factory valve behavior.

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. Drop the hammer with the valves closed and SwitchPath sings a proper M anthem. If you were to leave the valves closed at all times after equipping SwitchPath, we wouldn’t blame you, it’s that good… all of the time.
The opened valve experience Open the valves and the S63’s roar is uncorked. Sport and Sport+ modes achieve the ultimate contrast in behavior when compared to comfort driving modes (valves closed). In Sport mode, the exhaust note is powerful, clean, and aggressive. In Sport+ mode, the same aggression applies… but with grin-provoking burbles…a lot of grin-provoking burbles.
If you’re looking for the best of both worlds and want to retain your factory valve behavior all while gaining peace of mind (i.e. emissions compliance), look no further than SwitchPath.
Tips The SwitchPath and Track Edition Exhausts feature statement-making quad 4-inch double-walled, slash-cut tips in either chrome silver or diamond black, complete with a stamped AWE logo.
