Making a straight through, decat, exhaust for my 1998 Toyota Landcruiser Amazon 4.2 liter turbo diesel 6 cylinder, 1HDFTE

The exhaust was rotten and broken, so I replaced some of the sections with large bore straight pipe with my MIG welder. I removed the catalytic converter from the pipe which will increase gas flow and give the engine a little more power. This will only work with older diesel engines. Removing the cat from a modern diesel engine will actually decrease power and effect emissions.
