Welcome to Version 2 of the Valvetronic Designs E9x M3 exhaust system. Version 2 brings on new improvements that push us past the competition. First is a return to Vacuum valves. These valves have proven to be far more reliable than electronic ones. We have also improved the sound quality to give a more pure driving experience to make this system the best on the market for the E9x platform. These systems are fully mandrel bent for maximum flow and are constructed out of T304 stainless steel, the highest quality material on the market. Our dream is to offer the BMW community an incredible valved exhaust without charging the dreaded "M tax" and that dream has come true. For far too long these systems have been out of reach for most people, but no longer. This system comes with everything you need to have your E9x M3 sound like a beast on your favorite backroad, or cruise to the shops without alerting the authorities. Your time to take control of your E9X M3 sound is now.
You now have the option to pair your Valved rear section with the best sounding mid pipe all in one place.
*FORWARD X-PIPE (TRADITIONAL V2): 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 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.
*Central X-pipe (OEM X-pipe) (LIMITED EDITION): Our central X mid pipe moves the x back to the factory location and puts the resonators in front of the X pipe to properly smooth exhaust tones before the merge point. These developments culminate in a very enjoyable deep sound experience with a slightly more exotic flare up top compared to the V2.
Sound tones are very similar in each setup due to the same resonators being used. You can not go wrong with either setup!
For those who choose the catted version, you are in for a treat. (TRADITIONAL V2 ONLY) Cats are located in the OEM location to aid with the emissions process. a 200 CELL EURO 6 Certified cat configuration is used for ultimate quality and flow.
