Exhaust IPE / FI

Wondering if anyone can assist.

My understanding with IPE / FI exhausts they are now using the OEM button instead of their own button for the valve control. This means the valve will close while the car is stationary
at the lights as per German EU regulations and therefore your G63 will always be quiet while stationary. Unlike older model vehicles without this OEM button, FI or IPE would provide you with a button on your keyring and the bypass will only be active when you push the "off" button on your remote.

Does anyone know a way around this problem ? I don't think FI or IPE recognise this mistake and support is very limited with this question.

Both brands we sell and yes they use the OE button and OE valve module. But from what we remember, the last G63 had the exhaust open/close button inside where you can open/close even at stationary.

Let us know if you have any further questions.

Thank you!

That's not correct. the "Open" OEM button automatically partially closes the Valve stationary.

Ah got it. Like I said, it's been a while since we last did a G63 exhaust so I forgot LOL =)

Does anyone have any feedback negative vs positive of the OEM valve controls and the ones from IPE or FI?
