Since there has been a bit of interest in the whole "aftermarket headpipe contacting the driveshaft" issue, I thought I would post my findings.

I went back to the muffler shop after I found the drive shaft was grinding the down pipe after installing the Banks header and custom down pipe. They bent it over as close to the oil pan as possible and since then it hasn't rubbed. I have yet to take it 4wheeling, so I will update this post if I find out it does rub while wheeling.

Here are some pictures of the head pipe and exhaust after the finished install (the bulge is some smog part I didn't want to eliminate in order to maintain a smog-legal status... I don't know or care what it's for, but if the smog guy wants it there I guess I'll leave it there).




Anyways, if you don't want that custom head pipe to contact the driveshaft, it better be darn close to the oil pan.

If you want to see the whole header/cat-back install, here is a link.

Are you talking about that stupid bulge in the pipe? I am not sure what the heck that thing is... but I told the muffler guy that if he thought it was a required smog part for the 1998 Cherokee to keep it in the pipe... so I guess he did. When I picked up my Jeep the guy who did the work wasn't around, so I never had a chance to ask him what the purpose of that thing was. If you buy a new stock downpipe it's not there. But my stock downpipe had it and I know that no one ever did any muffler work on my Cherokee since I am only the second owner and the original owner said he never did anything to it. Could it be a pre-cat? That is a word I hear thrown around for my era of Cherokee.

i think that the "bulge" may be type of catalytic converter required for California emissions (could be wrong idk)
