H8PVMT Posted June 26, 2012 Share Posted June 26, 2012 I need two band clamps to put exhaust back together, one will go where the flange connects the down pipe to the cat, the other after the muffler, have to order and install by Wed so want to get it right 2.25?

Eagle Posted June 26, 2012 Share Posted June 26, 2012 If this is for the MJ, the downpipe is 2-1/2" to the cat flange. The cat is 2-1/2" inlet and outlet, and the connector necks down to 2-1/4" between the cat and the muffler. The muffler is 2-1/4" inlet and outlet.

mountainman Posted June 26, 2012 Share Posted June 26, 2012 Measuring tape acrossed the pipe to make sure? :dunno: Link to comment Share on other sites More sharing options...
Eagle Posted June 27, 2012 Share Posted June 27, 2012 Measuring tape acrossed the pipe to make sure? :dunno: Are you asking me or H8PVMT? I don't have to make sure. I have replaced enough exhaust systems on 4 liter XJs and MJs that I am sure. If you doubt me, go measure for yourself. Just be sure you're measuring OEM or OEM replacement parts, not custom parts. Ask me about 2.5 liter XJs and MJ and I won't be so sure, because from the several I have had go through here the size of at least the tail pipe changed from year to year. If they changed the tail pipe, I don't know if they changed the exhaust pipe and catalytic converter with it, or if those stayed constant. Link to comment Share on other sites More sharing options...
