Description
Take complete control of your exhaust sound with the MAD Exhaust Valve Controller Essentials, a simplified, plug-and-play exhaust valve control system designed for enthusiasts who want convenient access to their preferred exhaust valve positions. Compatible with select BMW F-Series and G-Series vehicles, Toyota Supra A90/A91 models, and MINI models equipped with electronic exhaust valves, this controller allows you to manage exhaust sound independently of the factory system's automatic adjustments.
Unlike the factory exhaust valve system, which adjusts valve positions based on driving mode, throttle input, and emissions requirements, the MAD Valve Controller Essentials gives you direct control over your exhaust valves. Choose between fully open, partially open, fully closed, and factory operating modes to customize your exhaust sound according to your driving preferences.
Four Core Exhaust Valve Modes
The MAD Exhaust Valve Controller Essentials features four practical valve control modes operated through the included remote controls.
-
Top Button – 100% Open: Opens the exhaust valves completely for maximum exhaust volume and a more aggressive exhaust tone.
-
Middle Button – Toggle Control: Switches between 50% open and 0% closed valve positions, allowing you to alternate between a balanced exhaust sound and quieter driving.
-
50% Open Mode: Provides a partially open valve position designed to balance exhaust sound and help reduce unwanted drone.
-
0% Closed Mode: Closes the exhaust valves for a quieter, more controlled exhaust sound.
-
Bottom Button – OEM Mode: Restores the factory exhaust valve operating behavior, allowing the vehicle's original system to control the valves.
These four practical operating modes provide convenient exhaust sound customization without unnecessary complexity.
Plug-and-Play Installation
The MAD Valve Controller Essentials is designed for straightforward installation using OEM-style connectors and power supplied directly through the factory harness. The included extension harness connects inline with the factory exhaust valve motor connector.
-
No wire cutting required.
-
No separate power or ground tapping required.
-
No permanent vehicle modifications required.
-
Simple inline connection to the factory exhaust valve motor connector.
Unplug the factory connector from the exhaust valve motor, connect the MAD controller inline, and complete the installation without cutting or splicing the factory wiring.
Construction, Protection, and Reliability
The MAD Exhaust Valve Controller Essentials is designed for dependable operation in demanding automotive environments.
-
IP68 Waterproof Rating: Provides protection against water and dust, making the controller suitable for appropriate trunk or under-vehicle mounting locations.
-
Military-Spec Wiring Harness: Features a heat-resistant, fire-resistant protective sheath designed to improve wiring protection and reliability.
-
Memory Function: Retains the last selected valve setting after the vehicle is restarted when using the 100% open, 50% open, or OEM modes. The standard memory function does not retain the fully closed setting for startup.
-
Two Premium Remotes: Includes two remotes for convenient exhaust valve control.
-
HomeLink Integration: Supports convenient exhaust valve control through the vehicle's HomeLink buttons.
-
Factory Mode Override: Allows switching between factory valve behavior and the controller's available exhaust valve positions.
-
Included Dummy Plug: Supports installation on vehicles with a single exhaust valve. For dual-valve setups, the dummy plug is used on the passenger-side OEM harness.
-
Customizable Exhaust Sound: Allows drivers to adjust exhaust valve positions to tailor sound levels and help manage unwanted rasp or drone.
Important Memory Function Note: The standard controller remembers the 100% open, 50% open, and OEM modes only. If you want the exhaust valves to start in the fully closed position, select the MAD-101 controller instead.
