MotorCom - OBD Plug & Play Exhaust Valve Controller for BMW, Alpina, or Toyota Supra

From the factory, your BMW, Alpina, or Toyota Supra automatically closes its exhaust valve based on drive mode, speed, and RPM — suppressing the deep, raw sound your engine was built to produce. MotorCom keeps the valve permanently open, giving you a consistent, full exhaust note every time you drive. Developed by the team behind BimmerCode and BimmerLink, the most trusted tools in the BMW community, you know this is built to the highest standard.

Installation couldn't be simpler — just plug MotorCom into your OBD port and you're done. No coding, no workshop visit, no modifications required. Optional app control lets you configure everything straight from your smartphone. Plug in, start driving, and let your car sound the way it always should have.

How it works

Step 1

The MotorCom module simply plugs into your cars’s OBD port — no wiring required.

It can be removed at any time without leaving a trace – your vehicle remains completely unmodified.

Step 2

MotorCom runs in the background and keeps the selected exhaust valve position permanently active, independent of the driving mode.

The setting is automatically restored at every engine start, and the exhaust valve can be controlled at any time via the MotorCom app on smartphone or smartwatch, regardless of the selected start mode.

Make the Most of MotorCom

The optional MotorCom app lets you configure and control the exhaust valve, update your device, and access support at any time.
