Introducing the highly anticipated BMW G8X Titanium Valved Exhaust for the M3/M4!

Constructed entirely of CP Grade Titanium, fully tig welded and back purged; this exhaust not only looks great, but is lightweight and performs!

The full weight of the system came in at 32 pounds with all hangers and brackets! That comes in at a staggering 50lbs of weight savings with full 3” dual mid-piped exhaust!

Optimized for flow with minimal bends, this system uses 3” CP grade tubing with our unique muffler design giving it a very pleasing sound even with the valves closed!

What about valves?

Our system also utilizes the OEM valves which retains full factory functionality. No need to wire in a controller or carry a remote control with you. Let your car do what the engineers at BMW designed!

Our valve housings are designed and engineered in house and brutally tested. No spring clip or Chinese mechanism to adjust or deal with.

All systems are 100% made in the USA 🇺🇸 by hand, by us!
We don’t stamp our logo on a product made overseas.
