Hey guys, I picked up a 2.5” cat back exhaust system off of jegs the other day, and I’m trying to find a catalyst that will mount to the front pipe (slip fit) and connect to the muffler without any extra pipe expanding tools. I believe a 2.5” pipe will fit into the muffler inlet, I just need a universal type catalyst. Seen a few online but not sure of size to fit the front pipe.

Thought stock exhaust on an XJ was 2.25" ?
 
It is. Bought mine with 2.5” exhaust, with cat removed. The muffler rotted out on the ends, and I picked the new one on sale from Jegs. Couldn’t beat the price. Want to put it back together with a cat.
