"Yep, I remember the same "good ol' days"...there weren't none of them there dern new fangled wire weldin' machines...we held our exhaust systems together with CLAMPS, dang it...and BEER CANS...and BAILING WIRE if needed"

Dang - I had that same exhaust on an ol' Dodge P'up.

It was modular in design so that whatever piece was leaking this week could easily be replaced.
