Description
The MAD BMW G87 M2 4" Fat Boy Midpipe is engineered to deliver maximum performance and a refined yet aggressive exhaust note for the S58-powered G87 M2. Designed for enthusiasts who demand optimal flow, this midpipe features a full-length 4" center section with a minimum 3" diameter throughout, eliminating restrictions and improving throttle response.

Installation is simple and reversible thanks to the factory cut point and clamp system. The kit includes 3" and 2.75" reducer couplers to ensure compatibility with both factory and aftermarket axle-back exhaust systems.
