We’re proud to present the all-new, emissions-compliant AWE Catback Exhaust Suite for the BMW F8X M3 and M4.
SwitchPath™:
We made the S55 sound epic with the valves closed, and with them open… again! All while remaining emissions-compliant. Presenting the second generation of SwitchPath™ Exhaust for the BMW F8X M3 and M4.
Minimal bends, maximum flow, and push-button attitude. The SwitchPath™ Exhaust is a true catback configuration comprised of 3-inch and 2.5-inch U.S.-sourced T304L stainless steel, 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.
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 S55’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. 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 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 second-generation catback 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 22.5lb 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)!
Tip Options:
The SwitchPath™ and Track Edition Exhausts feature statement-making quad 102mm double-walled, slash-cut tips in either chrome silver or diamond black, complete with a stamped AWE logo.
