by large oval,I am assuming he is talking about the muffler or the cat..Only thing about getting one from the junk yard is that it might not be much better than what you have now..I usually build my own exhaust but if I was going to buy one,I would probably go to a local muffler shop..I have no idea about buying one
Cut if off n stick a Flow Master Super 40 series in there!!! The muffler is about 80-100. You'll need to rent a tool at Auto Zone, it's an exhaust pipe cutter. It's like 30 bucks but u et ur money back when u take it back. Buy a coupler from your exhaust pipe to the muffler and a short down pipe for the other side. It will drop before your axel if you do it right. And it'll sound mean! All I. You will probably spend under 150 dollars in the muffler, coupler, down pipe, and the little u-bolt fasteners. It should take about 2 hours all in all. There are a ton of videos on how to do it. Cut the muffler off on the side closest to the engine about 3inches away from the muffler towards the engine. Put the coupler there and then the muffler then the down pipe n tighten the crap out if it. When you save up some more money have it welded in place. It's money that will be well spent.

Buy a tailpipe that is prebent should be about $50, a muffler of your choice ( a cherrybomb glasspack is $50 and will give good sound and flow), and some sections of straight pipe. Put a piece of pipe from cat to muffler, then a piece from muffler to tailpipe, and your done, $100-120 from a local autoparts store
Sounds like all you need is a new muffler. You should be able to have a local muffler shop do that for under $100.
Mine was the same way. The seams rot out on the stock mufflers after a decade or so. I had a local muffler shop install a new stud in the mainfold, new pipe from the manifold back to a 30" glassy. I opted to reuse the original tail pipe as it is still in good shape. Charged me $60.

Really? Not to push the issue-I'm honestly not smart on this subject--but I thought it varied state by state. What exactly does the cat do? And why has it been said that it helps to remove it?
Edit: No rude tone inferred there. I'm not trying to push the issue. Just trying to understand how the engine works. This jeep is my trip to the mechanical world. Also I'm in the service, and though I don't live in an emissions-concerned state, I don't want to cause more work for myself down the road when I move. Thanks.
some states enforce it and some may not but it is a Federal law..basically the cat is supposed to help burn fuel that the engine did not..with age a cat can get clogged and reduce exhaust flow,which will reduce power...Then it is time to replace it
