On this page, you are looking at the Extreme Turbo Systems Electronic Valve Simulator. This simulator has been designed for those of you who have deleted the rear exhaust valve. If the valve is not plugged in the BCM, then it will not allow you to select different drive modes. With that said you will need this connector to be plugged into the connection where the exhaust valve was originally placed so the drive modes can continue without issue.

These will be sold individually.
