Welcome to the party in the back. Presenting the AWE Exhaust Suite for the BMW G8X M3 & M4
The Options:
SwitchPath™:
Presenting the first AWE SwitchPath™ configuration for BMW to incorporate patented drone-canceling 180 Technology®.
No drone, minimal bends, maximum flow, and push-button attitude. The 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.
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 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.
The opened valve experience:
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™.
The Track Edition:
AWE’s Track Edition takes all of the precision engineering and performance of its SwitchPath™ counterpart, minus the valved muffler in the rear. The result is a constant “valve open” mode, at an affordable price. If you’re craving rich and rowdy tones at all times, and a hefty 22 lb weight savings, this is your dose of steel.
The Track Edition Exhaust, also 50 state legal like its SwitchPath™ sibling, comes complete with AWE valve simulators to accommodate your factory exhaust valve motors. Happy ECU, happy life.
Note: This version is known to get rowdy, and may be too much for many. For that reason, this particular version cannot be returned due to sound preference. Prepare yourself (Sport+ mode can be pretty raucous)!
The Non-Resonated Performance Mid Pipes:
Ditch the factory mid section and replace it with two 3”, non-resonated mid-pipes designed to up the ante in the aggression department. Mate the mid-pipes to the SwitchPath™ or Track Edition Exhausts if you prefer the party to start right behind the factory secondary catalysts.
Tips:
When it comes to showing off the party out back, each exhaust comes complete with quad 4.5” double-walled, slash-cut tips available in chrome silver or diamond black.
Very important fitment notes (please read this too):
Mid Pipes: AWE’s Non-Resonated Performance Mid-Pipes are designed to be paired to AWE Exhausts only. Due to varying cut points, they’re not guaranteed to work with another manufacturer’s exhaust configuration.
Exhausts: AWE Exhausts feature inlet adapters to mate to the factory mid-section. When pairing AWE Mid-Pipes to the SwitchPath™ or Track Edition Exhausts, the aforementioned adapters are not needed. Due to varying cut points, AWE Exhausts are not guaranteed to mate with another manufacturer’s mid pipes.
Valances: AWE Exhausts are confirmed to fit all factory valances.
