Valvetronic Valved Sport Exhaust System For F12 BMW M6

T304 Stainless Steel or Grade 5 Titanium with Vacuum-Operated Valves

The BMW F12 M6’s S63 4.4L twin-turbo V8 delivers exceptional performance, but its factory exhaust doesn’t fully capture the car’s aggressive potential. The Valvetronic Designs Valved Exhaust System transforms the M6 into a dual-personality machine—capable of refined, luxury cruising or spine-tingling aggression at the touch of a button.

Building on the success of our F10 M5 and F06 M6 systems, this exhaust connects to OEM or aftermarket free-flow downpipes and is engineered for perfect fitment, improved flow, and a signature sound that defines the Valvetronic experience.
