MAD Exhaust Valve Controller Essential - BMW G-Chassis & F-Chassis

Product Details

Take full control of your exhaust sound with the MAD Valve Controller Essentials, a simplified, plug-and-play solution designed around the valve positions enthusiasts use most every day.

Unlike the factory system, which constantly opens and closes the exhaust valves based on drive mode, throttle input, and emissions requirements, the MAD Valve Controller lets you lock the valves exactly where you want them. The result is a more consistent exhaust tone, better sound control, and a driving experience that matches your preferences.

4 Core Valve Modes (Simple & Effective) - This controller features four practical valve modes, easily controlled via the included remote:

• Top Button – 100% Open - Valves fully open for maximum sound and aggression.
• Middle Button – Toggle Control - Switches between the two most commonly used positions:
  • 50% Open (balanced sound, reduced drone)
  • 0% Closed (quiet, controlled driving)
• Bottom Button – OEM Mode - Returns the exhaust to full factory behavior.

100% Plug-and-Play Installation (No Wiring, No Hassle) - Installation couldn’t be easier. The MAD Valve Controller Essentials uses OEM-style connectors and draws power directly from the factory harness. Simply unplug the factory connector from the valve motor, plug our controller inline, and you’re done.
