AWE Tuning BMW F8X M3/M4 Track Edition Catback Exhaust – Diamond Black Tips – 3020-43087

Description

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 its that good. Open the valves and the S55s 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 burblesa 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.This Part Fits:YearMakeModelSubmodel2015-2018BMWM3Base2015-2020BMWM4Base2019-2020BMWM4CS
