Dahler BMW Exhaust Flap Valve Control Module V2 – Flap Control X (2025 Model)

The Dahler Valve / Flap Controller for BMW & BMW M Cars Allows You To Manually Open & Close Your Exhaust. Full Open Valve Sound. Start Mode Memory.

From factory, certain later generation F & G Series BMWs don’t allow you full control of your exhaust system in terms of the valves / flaps that control the sound. The Dahler module is a simple system that allows you full control over the exhaust to get it’s true soundtrack whilst driving.

The controller is a plug-and-play system that installs directly into the existing OEM valve modules situated on the exhaust system.

One of the best features of this system is the memory function where the module leaves the valves in the position the car was shut-down in. For example if you want full noise on first engine start to really show off your exhaust then this will be perfect for you.

Depending on your vehicle you will require either the 1 flap or 2 flap system which can be selected from the drop-down above. If you’re unsure of what your vehicle has, please get in touch directly.

Please note that this is for the newer V2 (2025) model that is now IP68 rated.
