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 free-flow 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 included controller ties into the factory harness for full, on-demand sound control.
Large X-Pipe Crossover: Enhances scavenging for improved mid-range punch and a cleaner, more harmonized tone.
3.0" Mandrel-Bent Tubing: Reduces back pressure and sharpens throttle response.
Vacuum-Operated Valves: Proven durability and rapid actuation for seamless sound transitions.
Valves Closed: Refined, near-OEM volume for daily driving and highway cruising.
Valves Open: Deep, assertive V8 character with a motorsport edge.
Controller Integration: Key fob control plugs into factory valve circuitry for reliable operation and complete control.
Materials: T304 stainless steel or ultra-light Grade 5 titanium.
Weight Savings vs. OEM: –21.7 lb (Stainless) / –54.8 lb (Titanium).
Craftsmanship: Precision TIG welds; smooth, high-flow routing.
Tips: Multiple finishes available to complement your M5.
