Welcome to the Valvetronic Designs E9x M3 Titanium Program—the ultimate expression of craftsmanship, performance, and exclusivity. As pioneers in the valved exhaust industry, we have pushed the limits of materials and manufacturing to deliver what we believe to be the finest titanium exhaust systems in the world.
Unlike mass-produced alternatives, our Special Ops program exists for those who demand a system tailored to their vision—an exhaust that is as individual as the driver and the machine it’s built for. This is not simply an upgrade; it’s a statement of engineering excellence.
Constructed from aerospace-grade Ti 6Al-4V (Grade 5 Titanium), this system delivers exceptional strength at an ultra-lightweight. The result is a 51.7 lb weight reduction over the factory exhaust, significantly improving responsiveness and driving dynamics.
Our vacuum-actuated valves give you the flexibility to switch between an aggressive, motorsport-inspired roar and a refined, subdued tone for daily driving—putting complete control of your E9x’s soundtrack at your fingertips.
Material: Aerospace-grade Ti 6Al-4V (Grade 5 Titanium)

Welds: Precision TIG titanium welds for unmatched strength and aesthetics
Valves: Vacuum-actuated valves for instant sound control
Weight Savings: 51.7 lbs lighter than the factory exhaust
