ECS tuning lists the MPC tips carbon and titanium as fitting the stock M2, M3 & M4 but do not say it requires the MPC exhaust. Probably a typo on their part.

I found these tips (18302348836) but not sure if they fit the stock exhaust...

These tips(18302355889, 18302354364) Fit F22, F3x, F10, F12, 2 series and requires adapters (18302287042 or 18302287043 depending on model). So again not sure if these will fit the stock exhaust w/o the adapter.

I need to get off my butt, pull a tip and measure the stock exhaust pipe.

BTW, linking to ECS b/c they have the best pictures and descriptions.
The first one does say it needs the MPE (MPE apparently has 67MM pipes vs 70MM for stock - but your pics above suggested they were the same)...the third I am unsure about. The second is interesting bc it's an akrapovic part (cool) and a cross search of some other suppliers (non-OE) have the same tip sizes for F80/F10 M cars. A search seems to suggest the pipes on the bigger cars are 73MM vs. 70MM for the F8x cars. I guess that's small enough to where a clamp would suffice...just not sure on that.
