2021-2026 BMW M3/M4 OEM Exhaust Valve Controller

CURRENTLY NOT IN PRODUCTION

Enhance the sound of your BMW M3 Competition G80 with our advanced Valve Controller. Designed in USA . This device allows you to take full control over your vehicle's exhaust sound.

Once installed, you can manually open and close the AFD exhaust flap on your BMW M3/M4  any time. The controller operates with a simple remote or can be integrated with your car’s mirror buttons for seamless use.

Installation is straightforward and can be done by anyone with basic skills. The device plugs directly into the our exhaust module—simply remove OEM valve and replace with AFD valve module, connect it to the provided socket, then reconnect it to the exhaust flap socket. Installation involves accessing the trunk and under-body, utilizing an existing cable duct or sealing plug to route the device. 

Our Valve Controller Module is designed for safe operation, preventing permanent closure of the exhaust flap to avoid potential engine damage during high-throttle driving.

Features include:

OPEN FULL AND CLOSE 

**Memory Function:** With the remote, activate memory to retain your preferred setting (100% OPEN or STOCK) even after turning off the engine.

Our system is designed to integrate seamlessly without error messages or interference with the car’s data bus. The controller is plug-in diagnostic-reader proof and leaves no trace when your car goes for maintenance.
