Valvetronic Designs 2008-2013 BMW M3 (E9X) Midpipe

Welcome to the Valvetronic Designs E9x M3 midpipe. This midpipe is quite different than most, featuring a freeflow x merge right after the transmission tunnel. This design helps allow for maximum exhaust scavenging and power gains throughout the rev range. At the rear of the midpipe we have two 12-inch resonators to smooth the exhaust sound and provide noise mitigation. We also offer a catted version of the X-pipe for those who do not want to go fully catless. This X pipe is designed for those who want maximum sound and maximum Horsepower gains, it is not for the weak of heart.

For those who choose the catted version you are in for a treat. Moving the cats downstream and after the x pipe keeps that familiar high pitched F1 scream but allows for less overall volume and smell reduction. This Xpipe is perfect for those who want more power and more sound but who want to keep the smell down.
