Besides the quite strange grille setup, the G80 is a killer new M car, but like most, the sound is lacking. The Factory exhaust for the New G80 /G82 BMW M3/4 does not deliver the goods. We fix that with our single 3.5 inch mid-pipe. This mid-pipe incorporates an equal-length design that allows for a very enjoyable high pitch sound experience without having to modify your OEM rear section. This mid-pipe connects to OEM downpipes or free-flow front pipes if you choose to upgrade. It will not throw a check engine light and can be combined with any aftermarket axle-back. It's time for you to take control of your M3 or M4 sound experience with our mid-pipe. Never settle for anything but the best.

In addition to our mid-pipe, the system can be optioned with our Axleback for added sound and performance gains, as well as our valve control unit, allowing you to fully open and close the valves at the touch of a button. Constructed a T304 stainless, this system utilizes our familiar quad chambered muffler design in order to offer a very flexible sound experience for the G80 M3 and M4. The system runs 2.75 inches all the way back and is optimized for the best flow characteristics to improve sound and improve power through the rev range. To finish off the system, a beautiful set of double-layered tips come standard.

It's time to take your sound experience to the next level on your G80. Valvetronic Designs, does not compromise. Neither should you. 

The system is now available in ultra high-quality grade 5 titanium. Beware of other manufacturers selling cheap titanium systems. Ours differs by utilizing proprietary sourcing and construction techniques to ensure the ultimate quality of the system.
