Valvetronic Designs Valved Sport Exhaust System - BMW X7 M50i & M60i and Alpina XB7 (G07)
This Valvetronic Designs system is a 2.75" T304 stainless valved catback for the BMW G07 X7 and Alpina XB7 V8, built free-flow from inlet to tip. Valvetronic Designs tested both resonated and unresonated designs and settled on unresonated because it produced a more engaging sound, with pronounced pops and crackles on gearshifts, while staying drone-free in the cabin once the valves are closed.
An included electronic valve controller gives you command of both sound states independent of drive mode, and the system retains the OEM tip outlets so the rear end keeps its factory look. It connects to your OEM or an aftermarket free-flow downpipe and is a 100% bolt-on, reversible replacement for the factory system.
Why Upgrade
The unresonated design is the differentiator here: Valvetronic Designs chose it after direct comparison testing because it delivers a noticeably more engaging tone under load without adding cabin drone at a cruise. Full 2.75" flow from inlet to outlet removes the factory restriction, and the included controller means you're never locked into one setting.

Frequently Asked Questions
Does this fit both the S63 and S68 V8?
Yes. Valvetronic Designs publishes this system as fitting both engines.
Will this be loud and droney at a cruise?
No. Valvetronic Designs specifically chose the unresonated design because it stays drone-free in the cabin with the valves closed, while still delivering pops and crackles on gearshifts with them open.
Do I need a separate remote to control the valves?
An electronic valve controller is included with the system, so valve control is independent of the car's own drive modes.
Does this include the downpipes?
No. This system bolts to your OEM or an aftermarket free-flow downpipe; downpipes are sold separately.
I have the inline-six X7 40i — does this fit?
No. This listing is the V8 system for the X7 M50i, X7 M60i and Alpina XB7. The six-cylinder X7 40i uses a different Valvetronic Designs system with a different diameter; contact your BMP Tuning rep to confirm the correct part for your engine.
