Gives you instant control over your tailpipe exhaust flapper valve!

2012+ F & G Chassis BMW 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 driver's 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 into 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 take only seconds and it won't interfere with aftermarket tuning systems.

In addition to controlling your factory exhaust valve, this handy module includes many other useful features. For //M models there is an active sound MUTE option to turn off the engine noise pumped through your stereo system. For those with LED headlights, there is an LED HALO max brightness mode to brighten your angel eyes at night. In addition, there is an optional in-dash boost gauge allowing you to read your boost levels when racing. All of these features including the exhaust valve control can be independently enabled or disabled right from the driver's seat! We expect to add many more features to the device via free firmware updates that are loaded at home via a BMS DATA cable.

On M vehicles there are two of the above exhaust flaps, one on each side. These will both open and close simultaneously on M vehicles.
