2013+ F Series Models are equipped with an electronic valve in the tailpipe that helps control the exhaust sound according to a profile programmed from the factory. This handy plug and play module lets you take control of your flapper valve right from the drivers seat. Go from sounding 100% stock to an exotic exhaust system for a fraction of the cost with just one click of a button. Our seamless integration using the CANbus eliminates the need to install/tap wires, carry around external remotes, or physically unplug exhaust components. Just plug the module in to your OBDII port, tuck it under the carpet, and press the turn signal button to toggle between flap always open, flap always closed, and OEM operation. Installation and removal takes only seconds and it won't interfere with aftermarket tuning systems. Compatible with all tunes. Note vehicles equipped with a JB4 already have similar functionality built in.
