T304 Stainless Steel or Grade 5 Titanium with Vacuum-Operated Valves
Overview
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.
Why It Works
Vacuum-Operated Valves: Switch seamlessly between quiet, stock-like operation and a deep, aggressive tone.
High-Flow 3.0" Design: Reduces back pressure and improves scavenging for gains in horsepower, torque, and throttle response.
Material Options: Choose T304 stainless steel for durability or Grade 5 titanium for maximum weight savings and performance.
Sound & Control
Valves Closed: Subtle and refined for comfortable city driving or highway cruising.
Valves Open: Bold, commanding tone with pronounced turbo spool and overrun character.
Controller Included: Plugs into the factory harness for reliable, factory-like operation.
