Description
The MAD Valve Controller Essentials is a simplified, plug-and-play solution that gives you total control over your BMW exhaust valves. Unlike the factory system, which constantly opens and closes based on drive mode, throttle input, and emissions requirements, this controller lets you lock the exhaust valves exactly where you want them. The result is a consistent exhaust tone, reduced drone, and a driving experience tailored to your preferences.
Designed for enthusiasts who want ease of use without sacrificing functionality, the MAD Valve Controller Essentials focuses on the positions drivers use most, making exhaust management simple, effective, and enjoyable.
