Three steps. No workshop.
VALVED does not modify your exhaust — it takes command of the valve BMW already fitted to it. That is why there is no cutting, no tune, and nothing to reverse.
Why not just buy an exhaust?
An aftermarket system is loud all the time and costs thousands. A straight pipe is permanent. VALVED gives you the choice, on the exhaust your car already came with.

Questions, answered
Which M4 does this fit?
Which M4 does this fit?
The BMW M4 F82 coupe and F83 convertible, 2014–2020, fitted with factory electronic exhaust valves. The module plugs into the OEM actuator connector, so fitment is decided by that connector and its signal — not by the badge on the boot.
Do I need a tune or coding?
Do I need a tune or coding?
No. VALVED sits between the factory loom and the valve actuator and controls the actuator directly. Your ECU is never touched, nothing is flashed, and no coding is required.
Will it throw a check-engine light?
Will it throw a check-engine light?
The module is designed to keep the actuator circuit intact, so the car sees a valve that is present and responding. If you ever do see a fault, unplugging the module returns the car to factory behaviour immediately.
Can I still make it quiet?
Can I still make it quiet?
Yes — that is the point. You can hold the valves closed for a cold start, a late night, or a drive past the neighbours, and open them again whenever you want the full note.
How long does it take to fit?
How long does it take to fit?
Most owners are done in under fifteen minutes. Locate the actuator at the rear of the car, unclip the factory plug, seat the module inline, clip it back together. It only goes in one way.
Can I remove it later?
Can I remove it later?
In seconds. Unplug the module, reconnect the factory plug, and the car is exactly as it left Munich. Nothing is cut, drilled or permanently altered.
