the GPF is very restrictive
your other choice is an aftermarket exhaust
Sadly not an option where i live cuz would make the car non road legal after i remove the GPF

The OPF has nothing to do with the upshift burp. I have removed the OPF and still don't have the upshift burp.

You have to do a XHP transmission flash like Rui Motors said.

Apparently, by disabling the GPF/OPF function using BMW ISTA P, will bring back all the burple/shifting sounds that lacks on the EU version.

But I have not been able to find much information about how to do this and I doubt any car dealer shop thats uses ISTA will allow you to do this at them.

No you don‘t have to unlock the ecu to flash xHP.
