IAW BMW F + G Chassis Mini Supra MkV Exhaust Valve Controller

Unlock the Full Sound Potential of Your BMW G80 M3 G82/G83 M4 G87 M2 or F80/F82 M3/M4 with Infinite Autowerks' Valve Controller Module

Take full control over your BMW M's exhaust tone with our advanced Valve Controller. At Infinite Autowerks, we know how important it is to enhance your driving experience—and this module is a game-changer for sound control.

With our system installed, you can manually operate the OEM exhaust flap anytime with the included remote.

Simple Plug & Play Installation
Designed for convenience, the controller installs easily using factory connectors—no splicing or special tools required. Just unplug the existing connector, attach it to the module, and connect the remaining lead to the exhaust valve. The entire setup is done discreetly in the trunk and undercarriage using factory cable paths or existing grommets, avoiding the need to run wires through the cabin.

Smart Safety and Functionality
For longevity and engine protection, our system does not allow the flap to stay permanently closed under wide-open throttle. This safety feature ensures long-term reliability without compromising performance.

• One-touch Control:

  • OPEN – Instantly open the exhaust valves (100%)
