Evan@Tischer As I understand it, these are PN 18302468411, correct? They are designed for all F8X stock exhausts?

I have a question re PN 18302456072, which is the carbon tip for the M2C/M5 MPE and different than the carbon tips for the OG M2 and F80/2/3 MPE system. My understanding is that those MPEs use 67MM inlet, and stock uses 70MM. What I don't know is what the M2C/M5 MPE system uses. From some poking around on the M5 forums, it seems it may be the 70MM number.

I ask because 18302456072 appears slightly longer in pictures and has a longer carbon sheath. This would mean that if it fit the stock pipes on the M2C it wouldn't look as awkward as 18302468411 does from the side angle because you can see where the carbon ends as the tips are closer to the outside edge of the car. They may also stick out the back a tad further and not be so tucked under the diffuser. None of this applies to the F80/2/3 because the tips are more enclosed.

Any way you have 18302456072 sitting around and can measure inlet diameter and overall length? I'm hoping this is an unadvertised lucky mod. Thx!
