im running no muffler right now and it sounds great but ill be running a cherrybomb right after the cat with it dumped right before the axle. the cherrybomb sounds really good. nice growl to it.
I've used the Dynomax cat back system on my 96 and 99 XJs. I like the sound, but, here in PA, they rust out pretty bad after 3-5 years.

Go to Youtube.com and do a search for "Cherokee XJ Flowmasters". You'll find video's of the 40 and 50 series. You can tell the 50 series has a deeper sound to it. Hope this helps

I installed this kit with a new cat last fall. Love it.. i wanted something quieter than the Rusty's with Flowmaster and this fit the bill.
I do alot of backcountry two-track driving, checking out the scenery etc.. and noticed a few times i barely got a glimpse of a wild animal such as Bears because they heard me coming from quite aways out. I wanted to remedy that... and it's seemed to help.
Heres the kit at Summit $139.

I would suggest running it out all the way. The tail pipe emissions are somewhat caustic and will cause rust in the long term

yeah i know, thats why im coating the underside. the heat shield by the gas tank got cut off in the process of taking my old reciever hitch nut plate out so nothing there right now. i could build one but we will see..
