Sound & Control
Valves Open
Open the valves and the G87 M2 announces itself with an authority that belies its compact dimensions — a deep, turbocharged snarl that builds into an aggressive, layered howl as the tachometer sweeps through the S58's powerband. Boost transitions produce an audible rush of pressurized air, while abrupt throttle lifts reward the driver with sharp, percussive crackles that echo the car's motorsport intentions. It is an unapologetically loud, visceral experience that transforms every tunnel and overpass into a concert hall.
Valves Closed
In closed configuration, the G87 becomes a stealth performer capable of navigating residential streets, underground parking, and early-morning commutes without attracting a second glance. Exhaust volume drops to factory-equivalent levels, interior NVH remains composed at highway speeds, and the car presents itself as nothing more than a handsomely styled 2 Series coupe. The transformation is immediate, controlled entirely through the iDrive interface with no delay or awkward transition between modes.
Construction & Engineering
- Material: T304 stainless steel or Grade 5 titanium (Ti 6Al-4V) — full TIG welding with back-purge

BMW G87 M2 Valved Sport Exhaust System
S58 Twin-Turbo Unleashed | T304 Stainless or Grade 5 Titanium | OEM Valve Integration
The G87 M2 carries forward BMW's tradition of distilling M division performance into the most compact chassis possible, and this time the stakes are even higher. Powered by the S58 twin-turbocharged inline-six — the same engine family found in the M3 and M4 — the G87 produces 453 horsepower in a body that weighs hundreds of pounds less than its larger siblings. It is, by every objective measure, the most potent M2 ever built. Yet the factory exhaust system, constrained by increasingly severe worldwide noise regulations, wraps that extraordinary powertrain in acoustic cotton, delivering a muted character that fails to communicate the violence happening under the hood.
The Valvetronic Designs valved sport exhaust for the G87 M2 recalibrates the entire experience. Engineered specifically for the S58 engine's boost curves and exhaust gas temperatures, the system replaces the factory cat-back with precision-fabricated components that optimize both flow dynamics and acoustic tuning. The result is a significant increase in exhaust voice when desired, without the compromises — drone, rasp, or interior boom — that lesser systems introduce at the frequencies most commonly encountered during spirited driving.
Constructed from T304 stainless steel or optional Grade 5 titanium, each system is TIG-welded with argon back-purge and mandrel-bent to maintain consistent internal diameter through every turn of the G87's compact underbody routing. The electronic valve system ties directly into BMW's factory valve infrastructure, allowing full control through existing iDrive drive modes.
