They cut and re-used the one on the muffler end. It is 2.5"...if you take a look, the original mid pipe swells up to that size just before the joint. The front flange was replaced, as that is where the problem is. The front of the mid-pipe is very small, but you don't get to see just how small until you look into it from inside the flange. I don't have a deep enough set of calipers to measure, but I'd say the I.D. at the front flange is no larger than 1 3/4"!
IIRC, the guy that built the Mid-pipe said the 2.5" flange he used was for a Toyota truck.
