BMW SUPRA MINI PLUG & PLAY EXHAUST VALVE CONTROLLER

Enhance your vehicle's exhaust system with the MAD Valve Controller, the ultimate tool for customizing your exhaust sound and performance. Designed to override factory settings, this controller gives you complete control over your exhaust flap, allowing you to tailor the exhaust note to match your driving style. Unlike stock systems that adjust the exhaust flap based on driving modes and conditions—often prioritizing noise regulation. You can easily switch back to factory settings with a single click, offering unparalleled flexibility for your driving experience.

Now featuring our V2 controller software update! This cutting-edge tool empowers you to fully customize your exhaust sound with 4 Valve Positions.

With the new V2 update for G body M Cars, the middle button—previously fixed at 50% mode—is now user-selectable, offering even more flexibility:

New User-Selectable Modes: Choose between 0% (fully closed), 25%, 50%, or 75% valve positions by holding the middle button for 3–5 seconds. Save your preference by pressing any other button.

Complete Customization: Easily switch between your preferred settings, factory mode, or fully open exhaust for a driving experience tailored to your style.

Non M G body Vehicles are limited to 50% only mode for the Middle button.

F Body Vehicles prior to 2019 may not support the 50% mode function due to BMW programming. Only the 100% and stock functions will work on these models.

100% Plug-and-Play Installation:

Installing the MAD Valve Controller is effortless, thanks to its design utilizing OEM connectors that draw power directly from the factory harness. Unlike other units, there’s no need to tap into power or ground wires, making installation seamless and risk-free.

Simply unplug the current connector from the motor, insert our controller in between, and you’re good to go.

Built for Performance and Durability:

Built for durability and ease of use, the MAD Valve Controller is IP68 waterproof, making it safe for mounting in the trunk or underneath the vehicle. Its military-grade wire harness is equipped with a fireproof sheath, ensuring safety and reliability. The controller also features a memory function that retains your preferred settings, even after restarting the vehicle.
