Installed exhaust pipe and muffler. Exaust down pipe is from Midwest and center pipe is NOS. Muffler was on the jeep when I got it. I sand blasted muffler and used Duplo Flat Aluminum from Autozone. Exhaust manifold is painted in Duplo high temp flat black.
Not sure if the attachment of the muffler to rear cross member is correct but it fits very nice so I kept it as-is.

copper tubing
Nice work on the vent lines Dave. Looks like you used copper tubing. Was it easy to bend and where did you buy it?

Before I painted the channels I coated a piece of sheet metal with Rustolium high temp 2000 degree primer. I ran a bead from bare metal and over the paint and it only burned off at the bead. The rest of the paint was still solid. I rubbed with scotch bright and it didn't peel or flake. I'm going to top coat it with the same brand.
I'm painted the inside of my hat channels and will paint the sheet metal on tub before I spot weld channels on. I did the same on the repair pieces I made before they get welded in. The Aluminum color paint looks just like sheet metal.
The black pitting is result of the phosphoric acid. The sheet metal was pitted but still solid.

Finished welding in the new MWM hat channels. Hat channels fit as well as they look. Once again thanks to MWM.
I have so many hours into this tub reversing damage due to age, the elements and bubba. This is by far the most labor intensive part of the project. And to think that my tub wasnt' that bad... my hats off to you guys who replace major sections.

Hat Channels
Did you use a spot weld cutter to remove the hat channels? I noticed that there aren't any holes where the hat channels were. Every time i've removed body panels, I make holes all the way through the panels.

Hi Dave.
I used a spot weld remover from Harbor Freight and it worked really well. After the old channel is removed you have to grind off the tabs. No need to drill through the floor.
I had to weld in four patch pieces and the hat channels and that was about it. Not pretty but a good solid floor now.

Just when I thought I was done I found another damaged area. The hood was folded back at some point and left a huge separation in the metal. The previous fix was a few pounds of Bondo and rust so I torched off the old Bondo, cut out the section and welded in a new section as you can see. A skim of Bondo should finish it up.
