2.75" as mentioned. GM trucks have ran that size since the LS series 5.3Ls have been in them I believe so the odd size has been around awhile.

So the next question is would a 3" fit tightly over a 2.75 or is that too much of a difference?

Too much. If Summit doesn't have an adapter I would think a muffler shop could make one.

Summit should have an adapter for it. Auto parts stores definitely do.

Anything with 2.75 is hard to find.

Well I've seen 2.75" adapters at Advance cause I remember thinking "who the hell has a 2.75" exhaust?"
