Upgrading the center section of your exhaust often removes some restrictions, mainly catalytic converters, giving your vehicle both more power and more sound. We offer several different exhaust brands to get your vehicle sounding exactly the way you want it to!
Need a new brace to fit your larger exhaust for your G80 M3 or G82/G83 M4? This extended chassis brace from Valvetronic Designs provides extra clearance for larger exhaust pipes.
The MMX Performance Underbody Chassis Brace is engineered specifically for the F8x platform to eliminate the unwanted flex that plagues the factory mid-section. On the track or your favorite backroad, flex alters your alignment mid-corner, reducing tire contact patch.
