Muffler stuck & removing tailpipe



Any ideas on removing a rusty POS muffler? I can't get it removed from the CAT. I have used some "break free" stuff, pounded the shit out of it, and wiggled and waggled, but can't get it to move more than a 1/4 inch.

Also, what is the magic trick to remove the tailpipe. I have it free from the muffler, but I can't figure out the weird contortion needed here. I have tried everything my limited mental capacity can come up with, and still no love.

('87 YJ)

Any thoughts are appreciated and a six-pack to the winning answer!

Thanks...

Thanks for the quick replies...and the heads up on the gas tank thing...

I can see cutting the tailpipe to get it out...but getting the new one in prolly won't work as well that way (at least not without some duct tape).

So is anyone here good at solving rubicks cubes or anything that can tell me how to get it in place?

You can try removing the shackle bolts and lowering the axle.

You need to jack up rear
take the weight off
and it will lower the axle

Most exhausts are welded if installed right

yeah birdhunter has the right advise i had to replace mine and what i did was cut it off at the cat, left bout 5 inches and then jacked it up and threaded it out. then redid it in reverse to put the new one in, and then did some trimming on the old pipe so the new one would be as snug to the cat as possible. not to difficult but just have to be patient

My buddy had part of his ehaust get ripped down at the badlands. He couldn't get it off so we hooked a tow strap to it and I pulled it off with my jeep.
Get crazy!

When my exhaust decided to give up the ghost I jacked up the passanger side and then removed the bottom shock bolt to let the shock swing out of the way. Easy out and back in. Good luck.

If you are trying to salvage the cat.... take an air chisel and slice where the two pipes are slip fitted together, it will come right off then.

The clamp has put in crease in the pipe. You have to use a acetylene torch, get the fitting nice and red and it will come apart. As far as the pipe, like someone said, jack up the Jeep "body" not the axle and you will have plenty of room.

Got it....

All,

Thanks for the replies!

I ended up using a saws all and cut the old pipe out, then used it to cut the at the base of the muffler pipe that leads to the cat. That left me with just a piece of the muffler left, and cut into it a little, then used a pry to get it off, worked like a charm.

I took the suggestion of lifting just the driver side, and was able to snake the new pipe in....thanks again. (I have another unrelated question, but will start a new thread for it.)
