Manufacturer SKU: BMW.F9X.M5.M8.VSES.TI.TIBRT BMW F90 M5 Valved Cat-Back Exhaust System Grade 5 Titanium, 3.0" Tubing, Large Cross-Section X-Pipe, Electronic Valves Overview The F90 M5 carries on the S63 4.4L twin-turbo legacy—but its factory exhaust leaves the soundtrack on mute. The Valvetronic Designs Valved Titanium Cat-Back unlocks the voice this car deserves: refined when you want it, ferocious when you don’t. Built from Grade 5 titanium with 3.0" tubing from inlet to outlet, the system integrates seamlessly with factory control or runs on a standalone remote for full command in any drive mode. Finish it with your choice of premium tips and let the M5 sing. Why It Works - Forward, Large Cross-Section X-Pipe: Increases scavenging, smooths tone, and virtually eliminates unwanted rasp—especially on cars with aftermarket downpipes. - 3.0" Free-Flow Architecture: Reduces back pressure for sharper throttle response and a cleaner top-end note. - Valved Control, Your Way: Tie into the car’s ECU (Sport/Sport+) or use the included standalone remote for instant open/close in any mode. Sound & Control - Valves Open: Deep, exotic V8 character with crisp overrun and engaging burbles—without the buzzy, raspy edge common on other setups. - Valves Closed: Subtle, composed tone for daily commuting and highway cruising. - Flexible Integration: Choose factory valve integration or standalone remote control. Construction & Options - Material: Ultra-light Grade 5 titanium throughout. - Weight Savings: 56.5 lb lighter than the factory exhaust. - Craftsmanship: Precision TIG welds and smooth, high-flow routing. - Tips: Multiple finishes available to complement your M5.
