More exhaust...moving to the rear:

The old ladder bar attachment was in the way and had to be cut off - I'm going to pull the axle later and cut the rest of it off

This was the perfect tool for the job:

Some of the horrible brake lines that the previous owner rigged up...I had to drop them to get them out of the way

This is where he added an extra leaf - I'm guessing because of axle wrap.

Nice exhaust hangers.

if you do one more mod and exit between frame and spring to the side you eliminate 90% or more of the fumes jumping in the back, and never munched off road.

Just curious, why the double mount for the exhaust? (Both sides)
Just for better support. The inlet on the muffler is offset, so there may be some twisting forces. The pipes are very close to the crossmember and tub, so I wanted to (hopefully) prevent them hitting. Also, the rubber isolators will stretch over time, so having an extra isolator will help that too. It may not help or be necessary, but it was pretty easy to do

Thanks for the nice comment on the exhaust hanger 🍻


Like this? This is my 95 YJ - I had to exit the tailpipe there because of my Genright tank:

Basically, yes.

i’ll shoot a pic later.
After 15 months parked I’m finally pulling the blown transmission and rebuilding my spare.

Still knocking out the exhaust details...

I'm using the stock YJ tailpipe hanger, which is rusty.

I don't know if any of you have used Evapo-Rust, but I've had good luck with it.

This is after a few hours.

I cleaned up these two areas with a scratch wheel. No picture, but they got paint.

Removed for welding and painting:

Trying this for the first time. At $13/can, it's a little pricey.

Primed. No picture, but it got the top coat afterwards

I should get the other parts welded and painted soon. Hopefully, the exhaust will be finished and installed on the Jeep this weekend.

More exhaust work:
Mid pipe is fully welded, cleaned and primed:

Tailpipe primed (it was later painted, no picture):


Insulation wrap materials. I've never used any of this stuff before.


I just wrapped some targeted areas. This wrapped area is adjacent to the starter. You can also see one of the O2 ports that I added. I stopped wrapping at the O2 port because it was going to be complicated to get around that area.


Wrapping such small areas was pretty easy.



Oil Pan wrap. The pipe is closer to the pan than it looks in this picture:


Starter wrap:


After the front pipe was installed, I wrapped another area on the other side of the O2 port. I wanted to protect the starter a little more.

Very nice exhaust work!

I know it's after the fact, but I might have shoved some paper into the ends of the pipes to keep the paint out. Not totally sure if it matters much, but just something I noticed. 🙂

Good suggestion - I didn't really worry about overspray into the pipe at all, and I didn't do any prep work on the inside of pipes. Anything that got in there would likely have trouble sticking. Any paint in the pipes will probably just blow out or burn off pretty quickly.
