Get a full 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. At Valvetronic Designs, we do 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.
