Installation of our Exhaust Flap Control Module in your BMW M4 G82 can be carried out by anyone with a manual skill. The device is a direct plug in to the existing (OEM) harness. You pull out the original plug and connect it to the socket. The other plug is then connected to the socket on the exhaust flap and the connection is done.
