BMW’s move from the S85 V10 to the S63 twin-turbo V8 brought big gains in efficiency and speed, but the factory exhaust left the soundtrack behind. The Valvetronic Designs Valved Exhaust System restores the drama, delivering a sharper, more engaging tone with genuine GT composure when you want it. Connecting to OEM or aftermarket downpipes, this system runs 3.0 inches from inlet to outlet and features a large X-pipe crossover for superior scavenging and response. Exhaust flow then passes through our valved mufflers, exiting via your choice of premium tips. A vacuum-actuated valve system with an included controller ties into the factory harness for full, on-demand sound control.

The F90 M5 continues the powerful legacy of the S63 4.4L twin-turbo engine, yet the factory exhaust system often keeps its true acoustic potential far too quiet. The Valvetronic Designs Valved Titanium Cat-Back system finally unlocks the aggressive soundtrack this car deserves, providing a refined tone for daily driving and a ferocious roar when you decide to push the limits. Crafted entirely from premium Grade 5 titanium with 3.0" tubing from the inlet to the outlet, this lightweight masterpiece integrates seamlessly with your factory controls or operates via a standalone remote for absolute command over your driving experience. Engineered for maximum performance, the forward-mounted, large cross-section X-Pipe significantly improves exhaust scavenging and smooths the overall tone, virtually eliminating unwanted rasp, which is particularly beneficial for vehicles equipped with aftermarket downpipes. This free-flow architecture reduces back pressure to deliver sharper throttle response and a much cleaner note at the top of the rev range. For effortless versatility, the integrated valve control ties directly into the car’s ECU through the Sport and Sport+ settings, while the included standalone remote ensures you can instantly toggle between a stealthy profile and an unrestricted scream in any drive mode.

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.
