FAQ

What is the P-HF1383?

It is an Akrapovic sound control kit that operates the valves on specific compatible BMW M3 and M4 Akrapovic exhaust systems.

Is this a universal valve controller?

No. It must be matched to a supported Akrapovic exhaust and vehicle configuration.

How are the valves controlled?

The kit supports control through the supplied remote and the compatible mobile application identified by the manufacturer.

Does this fit both M3 and M4 models?

It is cataloged for supported M3 and M4 applications, but engine, body style, OPF status, and installed exhaust part number must all be confirmed.

Does it include an exhaust system?

No. This listing is for the sound control kit, not the muffler, link pipes, or complete exhaust.

Will installation affect exhaust approval?

Akrapovic notes that manual valve control can affect the approval status of an otherwise homologated exhaust, so local rules must be checked before use.

Is professional installation recommended?

Yes. Correct wiring, routing, pairing, and exhaust compatibility should be verified by a qualified installer.

Can it be used on a stock exhaust?

No stock-exhaust compatibility is claimed. Use it only with a manufacturer-confirmed Akrapovic system.
