I found the answer after reading through some of the M2 forums and it turns out that the Aus version does have an opf. Basically all M135i in Aus are euro 6 compliant ☹
It presents an issue for me because I cannot go to my local exhaust shop and delete the opf without a tune done to eliminate running issues like error codes and/or the car going into limp mode.
There are two options so far that I know of that can get rid of the error codes generated when the sensors detect a difference in exhaust flow (due to the removal of opf)
1) a tune or
2) installing a manhart chip that disables the 02 sensor
So until I find a tuner or buy the chip, I will have to settle for an axle back exhaust.
I found this website WebETK that gives you more info on the opf's and other car parts in general. You will need to enter your VIN details to bring up your vehicle. S1DEA is the OPF code.
If anyone has any info on how to get more sound, please share!
I took a pic of what I think is the opf and resonator? Not sure yet

I was crawling around under my car last night trying to see what was underneath and my exhaust (uk) looks nothing like this. Your pic shows two separate looking parts to the exhaust where on my car it is one single larger and longer box. My car sounds nothing like yours either unfortunately!
