Isle of Man Green G80 M3 Competition - AWE Tuning Switchpath Exhaust System

No drone, minimal bends, maximum flow, and push-button attitude. The AWE Tuning SwitchPath Exhaust is comprised of 3-inch U.S.-sourced T304L stainless steel, a precision x-pipe, and a valved SwitchPath muffler tuned specifically for the S58. Beginning after factory mid pipe, the precision X-pipe immediately helps smooth the S58 of its rasp, deepening the tone before its refined further by the bespoke SwitchPath muffler in the rear.
 
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 with no drone at cruising speeds. AWE SwitchPath tech also responds perfectly to the many transmission settings and shift points in automatic 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.
 
Open the valves and the S58’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.  Thanks to the precision X-pipe, the rasp is still kept in check while allowing the exhaust note to reach full aggression.
 
If you’re looking for the best of both worlds (i.e. drone-free, clean aggression), and want to retain your factory valve behavior all while gaining peace of mind (i.e. emissions compliance), look no further than SwitchPath.
