So, my passenger side cat plugged last Friday after I had the muffler replaced on Monaday due to a broken baffle.
Had to begin a 700 mi drive on a Sunday so no time to take it to a shop.
Friday evening I grabbed a 3" exhaust tip, exhaust patch tape, hose clamps, and bean cans. Had a sawzall. My arc welder was 700 miles away.
Cut out the cat, was able to leave both upstream and downstream O2 sensors in the exhaust.
Rear cut was pretty square, front cut was badly angled. Had to do it with the blade upside down and I was in the dark. Cut the exhaust tip using a couple pieces of firewood and my knee as a vise.
Rear exhaust tape, bean can, and hose clamp assembly held the entire 700 miles. Front patch kept blowing, had a 3/4" gap in it. Added a ring cut and formed from a baking pan and tightened with bailing wire, helped a little.
Ended up using the jbweld exhaust patch stuff that comes in a foil package, it would hold for a few hours before it would blow. Usually when I was around 4000 RPM in 3rd gear. I think I went through 6 of them. Stuff is pretty toxic, comes with nitrile gloves. Got a lot of funny looks in parking lots with the kid pouring water on my hands and arms while I washed off. Has a 20min idle cure.
It was so loud when it would blow! Would lose a lot of low end torque. (All y'all knuckleheads with the stupid loud exhausts take note: back pressure matters, especially for lowdown torque)
Got lucky and didn't get a ticket coming through town on the way to the new house.
It got us home.
