G8x M3/M4 MIDPIPE

The Dinan Middle Exhaust for the G80 M3 and G82/G83 M4 introduces a more aggressive tone and an increase in volume over the stock system while retaining the factory muffler at a budget-friendly price point. It can easily be paired with the matching Dinan axle-back exhaust for further aural enhancement. This middle exhaust removes the hydro-formed factory center section from the secondary catalysts back to the axle-back, including both resonators, and replaces it with larger 3-inch T304 stainless steel tubing. In place of the forward factory resonator, Dinan incorporates a beautifully crafted X-pipe made from mandrel-bent tubing for minimum restriction. This X-pipe promotes even flow to both banks of tips and removes unwanted nuances in sound.
