Unlock Exhaust Sound Control and More with the OBDII CAN Flap Module for BMW

admin February 21, 2025No Comments

Modern BMW F and G chassis vehicles come equipped with an electronically controlled exhaust flap valve designed to modulate exhaust sound based on factory-programmed profiles. Now, gain instant command over your vehicle’s auditory experience with our plug-and-play OBDII CAN Flap Module. This innovative module empowers you to effortlessly transition from a stock-sounding exhaust to a more aggressive, exotic tone at the touch of a button, all without the hefty price tag of a full exhaust system replacement.

Our module seamlessly integrates with your BMW’s CANbus system, eliminating the complexities of wire splicing, external remotes, or manual disconnection of exhaust components. Simply connect the module to your OBDII port, discreetly tuck it away, and utilize your turn signal button to toggle between three distinct modes: flap always open, flap always closed, and standard OEM operation. Installation and removal are swift and straightforward, taking mere seconds, and crucially, it maintains compatibility with aftermarket tuning systems.

Beyond exhaust valve manipulation, this versatile module unlocks a suite of additional functionalities. For BMW M models, an active sound MUTE feature is included to disable engine noise amplification through the vehicle’s audio system. For vehicles equipped with LED headlights, an LED HALO max brightness mode is available to intensify the illumination of your angel eyes during nighttime driving. Furthermore, an optional in-dash boost gauge can be activated, providing real-time monitoring of boost levels during performance driving scenarios. Each of these features, including exhaust valve control, can be independently toggled on or off directly from the driver’s seat, offering unparalleled customization. Future firmware updates, conveniently installable via a BMS DATA cable, are planned to introduce even more features, ensuring your module evolves with your needs.

On BMW M vehicles, each exhaust bank is equipped with a flap. This module is engineered to control both flaps in tandem, ensuring synchronized operation for balanced exhaust flow and sound modulation.
