dAHLer BMW Exhaust Flap/Valve Controller

dAHLer BMW Exhaust Flap/Valve Controller is the perfect solution for your BMW to take control of your vehicle's exhaust sound.

This device allows the user to manually open and close your vehicle's factory exhaust valves at the push of a button. Plugging directly into the existing OEM harness, the daHler valve controller is super simple to install, requiring no coding. The valves are controlled using the supplied remote or can be programmed into your mirror buttons for seamless integration.

Please note: For safety reasons, your vehicle's valves cannot be permanently closed using the daHler controller as air restriction under full throttle may cause damage over time.
