Plug & Play exhaust valve controller

The MotorCom exhaust valve controller is developed and manufactured exclusively for racing vehicles and is intended for use in such vehicles only. Use in vehicles approved for public road traffic within the European Union is not permitted.

More Sound — Plug & Play

From the factory, the exhaust valve closes depending on drive mode, speed, and engine RPM – taking away much of your car’s sound. MotorCom prevents this automatic closing and keeps the valve permanently open. The result: a deep, consistent exhaust note and full control over your exhaust system. No coding, no workshop visit, and no complicated installation required. Just plug it in, start driving, and enjoy the sound.

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.
