that sucks.
coat hangers make excellent filler for exhaust systems with a fine torch tip. in fact that's MY preferred rod for exhaust systems if I'm not using the wire feed welder (flux core)
I got pretty good at doctoring up decrepit exhaust systems when I was buying Junkers on a regular basis.

I know a lot about a lot of things BUT I still have a lot to learn.
Life is what you make of it. So, why not make a working machine to make it easier.
