Stock exhaust diameter

Does anyone here have information on the ID (inner diameter) of the Z4M exhaust, starting from the headers all the way out to the muffler (part by part)?

2.25?

I'm seeing 60mm in a few searches, but they reference the e46. Not sure how similar z4m exhausts are. Also, not sure if headers collectors and same size as the section1...

I've measured my exhaust at 60mm OD for the rear section up to the mufflers, leading to an ID of approximately 57mm.
