Gain complete control over your BMW’s factory exhaust valves with the Valvetronic Designs Vacuum-Style Exhaust Valve Controller — a compact, plug-and-play solution engineered for drivers who want full authority over their exhaust sound without unnecessary complexity or cost. Designed specifically for BMW models equipped with vacuum-actuated exhaust valves, this controller installs directly into the OEM trunk-mounted vacuum solenoid harness, enabling you to manually open or close the exhaust flap at any time.

Unlike factory programming, which limits valve behavior based on drive mode or RPM, the Valvetronic controller gives you unrestricted control. With the touch of a button, enjoy a quiet and refined exhaust tone for daily driving or unleash an aggressive, performance-focused sound for spirited runs. The system is 100% reversible, requires no coding, and does not interfere with ECU functions.

This controller provides a factory-level fit and finish with zero permanent modification required. Simply plug it into the OEM harness, mount the controller, and enjoy a fully customizable exhaust experience.
