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.

Aurora ★★★★★

Took me 10 minutes to install and now the cold start sounds like it should have from the factory. Being able to flip the valves open whenever I want, without having to mess with the iDrive menus, is exactly what I needed for weekend drives.

Evelyn L. ★★★★★

The valve controller gives me total control over the exhaust flaps, and the difference in sound is immediately noticeable when I switch modes. It was straightforward to install and makes the G80 feel even more aggressive on cold starts.

Nicholas P. ★★★★★

Took a risk on this since it's currently not in production, and I'm glad I snagged one. The fact that it was designed in the USA shows in the build quality, and having full control over the exhaust valves makes every drive feel noticeably more aggressive.
