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. Front resonators are added to reduce rasp. 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 free flow. This X pipe is designed for those who want maximum sound and maximum Horsepower gains, it is not for the weak of heart. SOUND CLIP BEFORE AND AFTER MIDPIPE UPGRADE: For those who choose the catted version, you are in for a treat, a 200 CELL EURO 6 Certified cat configuration is used for ultimate quality and flow.
