BMW F-Series exhaust valve control unit for factory valved systems

Take charge of your exhaust butterfly with this plug-in CAN controller designed for BMW F-platform cars equipped with an OEM valve actuator. It connects at the diagnostic port and lets you command the exhaust flap from the steering column stalk button for louder on-demand sound or quiet cruising whenever you need it. No coding required. No wire cuts. Fully reversible.

We have run this unit on our own F-Series builds and customer feedback has been consistently positive. Owners love the sharper tone with the valve open, the convenience of a silent mode, and the factory-like integration that plays nicely with performance tunes and other upgrades.

Main benefits

  • Instant valve override through the indicator stalk button. Choose valves open, valves closed or stock behaviour.
  • Seamless CAN integration for smooth operation without warning lights or fuss.
  • Zero coding. No splicing. No permanent modifications. Simple plug-in at the OBD port and tuck away.
  • Enjoy a more aggressive soundtrack on demand, then switch back for motorway comfort.
  • Dual-valve M models operate both valves together for a balanced tone.
  • Change modes at a standstill or while driving.

Extra CAN features

  • Active Sound Design delete on M models to remove synthetic cabin noise.
  • LED halo brightness boost for vehicles with factory LED headlights.
  • Optional in-cluster boost display so you can monitor pressure on the dash.
  • All functions are switchable from the driver’s seat. Firmware updates supported with the BMS Data Cable.

How it operates

The factory ECU manages an exhaust butterfly to alter sound. This CAN-enabled module gives you manual override using the steering column stalk button so you can select valves open for maximum tone, valves closed for stealth, or default OEM logic. It feels stock because it communicates on the CAN network rather than hacking wiring.

Fitting and support

  • Plug into the vehicle’s OBD diagnostic socket. No tools needed.
  • Compact unit tucks neatly under trim for a clean install.
  • Switch modes with the indicator stalk button.
