I just purchased a 2000 XJ sport 4x4 4.0, and cannot seem to get straight answers from the internet on an exhaust replacement. I see 2.25" and 2.5" as direct replacements. how is this possible? I'm looking to replace the cat, pipe to muffler, muffler, and tail pipe.
Any help is appreciated.

On both my Cherokee and my Comanche there were sections of 2.5" pipe and 2.25" pipe. Personally I just go to a muffler shop and have him do my exhaust work. Much better than all the replacement kits I've seen, and if for some reason it does end up making contact somewhere I can go back to him and get him to fix it. On my Cherokee I have a flowmaster super 44 which fits without hitting, but is a good bit louder than factory. It is shorter though so you would need a short section of extra pipe. In my Comanche I have a thrush turbo muffler which was around $25 and is pretty quite. I think it maybe a little shorter than factory too, but there isn't much factory exhaust left on that truck so I can't say for certain. In my personal experience a muffler shop is better than a diy kit. I think with a muffler I was quoted a touch under $300 from header to bumper on my Comanche.

On my 2000,,its 2.5 into the cat,,2.25 out.
Me,, I dont mind working on exhaust stuff.
I do all my own work on the Jeeps. So DIY kits are cool for me..
But Satirical has a good point on having a shop deal with it.
If anything needs fixing he can take it back and they will fix.
Sometimes you just dont feel like dealing with it..

I ended up buying this off Amazon $28.00 shipped , It sounds mellow but I need to put on the tailpipe and button things up. This is 2 1/4 center inlet and a 2 1/4 offset outlet it fits up nice on a 2000 XJ . Also you have to add a little pipe in is shorter than you oem muffler.

Need new exhaust system; header, pipes, whole thing.
1993 Jeep XJ
I need a new system. The header has a hole and the pipes are cracked in two different places. I am thinking about just getting a new header and getting a local shop to make new pipes out of 2.5". I'll keep the existing muffler and cat. Don't really care about the sound more about fuel efficiency and power.
has anyone done this? What's the best header for the price in terms of fuel mileage and power? While I'm at it should I change out the intake manifold?

2001 header and down pipe question.
I've got a 2001 xj, with a crack in the exhaust manifold. Besides some grinding on the intake manifold, would a '99 header with a '99 down pipe bolt up to the rest of the exhaust piping. I realize I'll need to also put bungs on the down pipe to put the o2 sensors in.
I'm a semi decent fabricator, I'm just looking for an inexpensive route to take with this cracked exhaust manifold.
Thanks.
