Got the exhaust pretty much done today. Very tedious work... Had to lower the cab into the body, take springs out, and install driveshafts multiple times to check clearances. All is well though, no binding anywhere, even at full bump.
I started out by cutting the factory exhaust off the flanges so I could reuse them -
The hardest part was the beginning because I wanted to reuse the factory catalytic converters and o2 sensors, but it was extremely tight -
Progress -
At this point, I knew the muffler could only go one place, so I temporarily secured it and made the front legs merge in front of it -
Routing complete -
The back is extremely tight at well. I believe the factory exhaust on an 80 goes over the rear crossmembers. I didn't have room under the bed, so I had to wrap up and over the rear axle.
This is at full stuff, sitting on the bumps -
Almost done... Need to install o2 bungs, finish welding all seams, put in 3 hangars. Another huge project about complete though.
