Ok got my new exhaust today, measured the cat in bore and it's the same as the one on the jeep, also the tail pipe dia is the same. the only problem i can see is it's missing the rear hanger bracket but i can get one welded on. the exhaust i bought is for a 97 4 liter code xch3 , hope this helps anyone looking for a pipe for a 2.5 , update when it's fitted......
