The MAD Single Midpipe is a premium performance upgrade for the G8X M3/M4, built to improve exhaust flow and bring out a more aggressive note from the S58. Its single 3.5" design reduces backpressure and enhances the engine sound, with a direct-fit layout that installs onto the factory exhaust with ease.

Expect gains in horsepower and torque plus improved throttle response and acceleration — an ideal next step for enthusiasts on the street or track.
