BMW Stock Exhaust Valve Controller - BMW S58 Engine

Product Description Unlock the true voice of your BMW S58 engine with the BMW Stock Exhaust Valve Controller — a precision-built upgrade that allows full control of your exhaust valves for an uncompromised sound experience.

With this controller, you can fully open the valves anytime, unleashing a deeper, more aggressive tone and giving your M car the commanding presence it deserves. Perfect for startup revs, light accelerations, or car meets, this controller ensures the full character of your S58 engine is heard — without altering or removing your factory exhaust system. Engineered for seamless integration, the plug-and-play design connects directly to your OEM valve actuators, offering instant control via a wireless remote or in-cabin switch, maintaining all stock functions while adding full manual control.
