I can't seem to find a replacement for the pre cats. Some auto parts stores specify that they are for after 1/20/2000 mine was manufactured in 7/1999 but is a '00.

Be sure the problem is cat failure --CA carb-mandated units are extremely expensive, and you will probably have to go with OEM units, which run will run you about $2400 for the set.

dude ur problems the bosch sensors. Any after market o2s will burn out in our 97-01s. the sensing probes are to long and practically touch the inside of our down pipes. missing it by maybe 1/16".U need to go to the stealership and buy Mopar 02s only.
I went through this a year ago. i went through 3 02s and then got a mopar. took the aftermarket and the oem and compared them. the bosch's probe was longer than the oem 1. explained this to the master mech at the dealer and he said thats been a problem for the 97-01 cherokees.

^^^ NTK, thats what I meant. Got them from napa a couple years ago.
I figured those were bad and replaced with the bosch. When that didn't work I replaced the lowers with bosch. Def going to get oem a try before forking out $1200 for new pre cats

forget the the precat bs. my o2 was so rusted into the stock down pipe. so i bought a walker down pipe with out the precat. it was like 40 bucks at napa. if you have to replace the main cat i would just get a high flow from performance-curve.com I replace my hole exhaust for 180. bucks except for the header.all from napa and perf.curve.
i only paid 40 bucks for the cat and that was 2.5 years ago and still goin strong even for NJ strict emission laws. the precat was more of a sound ballancing fix more than anything else. your mpg and overall running condition will improve greatly with a free flowing exhaust. with the right turbo muffler; it will still be quiet if thats what ur worried about.
The only things i would buy from the dealer are electricall components anything else aftermarket is fine.

Completely over kill and not even close to being nesessary. you don't need the precats. so it would be rediculous to pay 2400 for something that is not needed and chokes your exhaust down.
