The new G90 M5 may be heavy, it may be controversial—and from the factory, it may sound like a vacuum cleaner—but Valvetronic Designs is here to change that. Introducing the first and finest aftermarket exhaust system for the G90 M5, engineered to unleash the incredible sound potential of your 800+ HP super-sedan.
Whether you’re in the mood for spine-tingling acceleration or quiet, refined cruising, our valved exhaust gives you full control over your car’s soundtrack. Designed, and developed at our headquarters in Pennsylvania, USA, this system is built for the enthusiast who demands nothing but the best.
Valves Open: Raw, aggressive tone with deep character and zero unwanted rasp—finally letting the S68 twin-turbo V8 sound as potent as it performs.
Valves Closed: Quiet, refined exhaust note perfect for commuting or keeping a low profile.
Electronic Valve System: Operated via stand-alone remote for instant sound control.
Signature Titanium Construction: Crafted entirely from Grade 5 titanium for maximum strength and substantial weight savings.
