Yes all European petrol engines will have it...

Noo, the one after the turbo is just the catalytic converter, the GPF/OPF is the one under the car that looks like a middle silencer.

This is a techincal document from BMW on the G29 Z4 (same exhaust principle and same engine as in the 320i in the Z4 20i). It clearly shows the OPF in the middle of it, and the catalytic converter is right after the turbo.

Thanks for this clarification.
I deleted my previous posts which were clearly a bag of rubbish.

Hi, I am new to this. I have the same on my 2019 330i. I assumed this is just a resonator? The above picture is the same set up on my car can someone confirm. I would love to remove the res to give me more sound!
