    With most of these XJ body types being converted to hyper-lifted rock crawlers, would love to see what others have done with your XJ daily drivers.

    Hi I recently bought a 99 WJ with the 4.0 I6 and did some maintenance on it and found a couple of cracks in my muffler welding which i will fix but in the meantime I removed it and just but a little exhaust end after the catalytic converter so the exhaust gases go down and not directly straight...

    About 4 years ago the weld between my catalytic converter and front exhaust pipe broke free from the original exhaust due to corrosion, so I opted to replace the entire exhaust system, manifold and all. Well, the only option I can/could find for the front pipe is made by Walker, and so far...

    So I'm about to install a Savvy Tummy tuck/skid and I still have my stock exhaust in there, though it's rusting out. Figured I'd install a new catback while I'm at it. Those of you with the Savvy underamor, what exhaust do you have and how was the fitment?

    My 83 CJ7 with a 4.2 needs some exhaust work done, the cat is rattling itself apart and there is some rust hole around the cat/muffler. I'd like to make the exhaust more free flowing, and am in debate on whether to just do it from the cat back, so new cat, muffler, and piping. Or to take this...

    Not sure if this is related, but my XJ has been acting weird since I replaced a damaged exhaust header. 1999 XJ 4DR, 4WD, 4.0 with 150,000 miles. The exhaust header was cracked wide open near the collector and I finally replaced it after the noise was just too annoying. The old one was...

    I've had my jeep sitting for about 3 months while it was being worked on (no engine work) and I went to start it and it seemed fine at first. Then there was a horrid burning smell and a plume of white smoke coming from the tail pipe. I pulled it out of the garage to the outside where it was...

    Ok- it's time to address the issue that I've never been 100% certain was really there or not.... After city driving (stop and go) of an hour or two in a day, I often seem to feel hazy and almost car sick in my 1985 CJ7. It is my good-weather weekend driver and I almost always have the top off...
