I stand corrected. I have just checked and oem is 75mm  |
Then I have to assume that the 74mm reference for the M Performance exhaust is inaccurate. I know tip diameters are mostly meaningless, but I wouldn't understand how BMW would commission smaller tips when bigger is generally perceived to be better when it comes to aftermarket exhausts.
