Installed some new shocks over the weekend and discovered the passenger rear is rubbing on the exhaust. Does anyone foresee any issues if I were to just cut the exhaust short where the red line is? It is pretty clear of anything in the area and would be pointing downward.
Do you see that big black thing right next to it? That's the gas tank the exhaust goes out from underneath the vehicle for a reason. I would find why its rubbing and fix that instead trying to save a buck. Just fix it right and be a happy jeeper.
Can't you bend the last hanger rod enough to make it clear? Astro-Jason's comment on the plastic gas tank's proximity is right on, the exhaust is close enough to melt it if it is cut off too close to the tank.
I had the same problem with my 02. Took it to a muffler shop, where they put it on a lift a showed me the issue. The aftermarket muffler was center in and center out. They explained that if I went to an offset in and center out it would move enough to stop the rubbing without any other modifications. I gave them the go-ahead. Been driving for over a month now with no rubbing.

I remember a guy did just what you're talking about. He was driving down the highway after being proud of his new mod. He noticed the gas gauge was low, pulled over at a station and was filling up. The gas went in the fill hole and out onto the ground. He had melted the gas tank, let 10+ gallons leak out on the highway, and was lucky he didn't catch himself on fire.
I'll see if I can find the link to thread. Remember, the exhaust coming out of the tailpipe is usually 450°F+ or so, with some pressure behind it.
i had that same problem on mine, but didn't know of it until 4 years later or so (i'm guessing this because i lifted the suspension and the kit included extended rear lower brackets for the shocks). i discovered the rub marks when i was doing my diff oil last december.
this actually resulted in my headers cracking within less than a year from each (went through 3) and was more evident when i considered looking back at the collector gaskets. one side was all mangled in this case.
as far as cutting the pipe, i know some guys cut it just short of the rear axle and throw on a turn-down tip/weld one on. it would be best if you didn't because of the exhaust fumes coming back into the cab. i'm not sure of your local laws, but here in HI, the tail pipe has to exit after the rear axle, as long as the exit is after the passenger cab. this does not apply to any jeeps except for the comanches.
i ended up redoing the exhaust system earlier this past Feb. new header, cat, muffler, and custom tail made to clear the shock. $400 all together
As I recall, I modified my rear hanger to scoot the exhaust over about 1/2". Unbolted the hanger bracket and added a ~1/2" of round bar (or maybe it was a section of a bolt). I also trimmed the exhaust tip off as I didn't like the limp wrist
Thanks for the advice, ended up taking it to a muffler shop this morning and had them cut it off, put an extra bend in and re-weld it back on. Took about 1 hour and $100. Plenty of clearance now.
