I was taking a look at the Thunderbolt cats, and they had a category for oval cats or spin/spun.. Not sure what that's about, as I said, this is my first time doing something like this.
I looked up the parts on performance-exhaust and this is the cat and muffler that they're saying work with it:

Is this a decent cat? Or should I go with the thunderbolt? If so, which thunderbolt one matches the fit?

Hey guys,
First time I'm doing a cat/muffler setup for my '98 cherokee. I'm looking around on performance-exhaust, but do I need a specific cat and muffler? Or would they all fit ? I would like a cat that's not to cheap and will last, but nothing too expensive either. Any suggestions?
Thanks

For a muffler OE is 2.25" Center / Offset. We use a 2.5" Center / Offset in our kits. However if someone is custom bending pipes for you pretty much any muffler will work.
Here is a page I threw together. It will show the OE exhaust for each Cherokee. Look at the clamp size before and after the converter, this will tell you the exhaust size. M214 = 2.25", M212 = 2.5" http://performance-curve.com/cherokee-2.aspx
The ovals used to be the standard for converter sizes. The spuns (round) came out to use on vehicles that an oval wouldn't fit on. It makes no difference if you use an oval or spun, it's all personal preference. Several vehicle manufacturers are starting to use spuns as OE now.

Thanks for all the info mudfrog, I'll be ordering my cat (and whatever else you have for the setup) through you. I've been hearing good stuff and I just saw your other thread. I'm lovin the prices (probably the first time I've said that in a while). Thanks again

which headers would you guys recommend, pacesetter or gibson? i have read reviews on both, they both seem good, but gibson seems better. my question is, is gibson worth the extra money? i already have a cold air intake and a cutback exhaust. i need to replace my manifold anyways so i might as well upgrade

No reason to spend a kabajillion and seven dollars on an exhaust header for a 4.0... my Dad's TJ has run one of these for almost 20k now...
