How do you US guys measure exhaust diameter?

OD or ID?

Need to know which it is because don't want to order the wrong Magnaflow parts.

Basically want to have a cat-back built with Magnaflow mufflers/pipes the same ID as the ssac 2.5".

Does that mean I should order the Magnaflow parts in 2.5" also?

Yes good question.....and it would also help a lot to translate these inches to mm. Handy for those EU types like us two :shifty:

Generally I'd say the US sites list ID sizes for exhaust pipework, but looking at this pic it looks like it's 2.5" OD.

ID of the ssac 2.5" is not 2.5" indeed. That's what got me wondering.

there was a discussion about that before. The measurements where most likely taken as the outer diameter of the exhaust pipe and not the inner.

YOu are just too fast Mark. I swear it wasnt there before!!
It wasn't, I said "looking at this pic" then used the thread url in the IMG tags (so it didn't show up obviously). I just edited it as it looks kinda strange speaking about a pic that isn't there :-\

See you're like Flash... super fast! LoL. I didn't know how to image the thing, but I thought I would just chime in on a fellow member. I posted it thinking you may have forgotten. hehe

Almost certain that OD is indicated every time.
