Take full control of your exhaust sound with the HM BMW Universal Exhaust Valve Controller. Designed to plug directly into your OEM BMW exhaust valve cable, this kit lets you manage your exhaust with ease using the included wireless controller. For an even more seamless experience, the valve controller signal can also be paired with your HomeLink buttons on the rearview mirror, allowing you to open and close the exhaust valves directly from your mirror without needing the remote. We highly recommend doing this; if you ever lose your remote, this serves as a backup. Choose from four different settings: - A: Fully open for maximum sound and performance- B: Fully closed for a quiet drive- C: 30% open for a balanced tone- D: Factory setting for OEM operation What sets our controller apart is its simplicity. No coding, no additional power source, and no hassle. Just plug it in, and it works. Compatible with nearly every BMW exhaust equipped with a built-in valve, this is the perfect solution for drivers who want flexibility without compromise. Whether you need a discreet cold start to keep the neighbors or your family happy, or you just want to enjoy a quieter ride, this controller has you covered. Every kit comes complete with batteries, all necessary harnesses, and everything you need for a quick and easy installation.
