EVC-SPORT is an electronic vehicle specific control module that is designed to be plugged into an existing electronic exhaust controller, either OEM or aftermarket exhaust system that use the same electronic exhaust valve controller. Thanks to the remote control you can choose to OPEN the valve, to CLOSE it or keep the AUTO function (to allow the ECU to operate the valve automatically). It is a simple plug and play unit that is undetectable and can be removed for either a service or if you want to restore the car back to the original state. EVC-SPORT is for the true enthusiast that would like to control and get the maximum sound from his car.
