'98 TJ- Help replacing cat
 

'98 TJ, 6-cyl, 5-spd

My cat has a very annoying rattle in it. Bought a new one that has the
omplete exhaust pipe already attached upstream of the cat. I was able
to remove the two bolts on the TJ between the header and exhaust pipe.
I also managed to get the rusted bolt off the clamp holding the muffler
to the back of the cat. But still can't budge releasing the cat from
the muffler. Not a helluva lot of room to twist and pull. Any good
advice on this?

Most muffler places just cut the pipe off and fabricate a coupler...... time
is money

Re: '98 TJ- Help replacing cat
 

Once the u-bolt has crimped the two pipes together you need an air
chisel to get them apart. The outer pipe has to be stretched or cut on
an angle and peeled off the inner pipe, it will not slip off.

Usually it is fastest to just cut the sucker and add a 4" 'butt'
coupling with two new clamps.

I managed to get my old cat off with an angle grinder for the big work
and a diamond cutting wheel on the dremmel for where the grinder would
not fit. Took a while to cut and peel pipe back.
