AWE SwitchPath™ Catback Exhaust for BMW F8X M3/M4 - Diamond Black

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. 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™.
