Exhaust clamps

[gregs78cam]

I bought a set of exhaust clamps quite a few years ago (10+) from a local place, I have been really happy with them because frankly they are awesome, they don't bend, and they are extremely easy to install, and i have been useing them with the same copper gaskets for those same 10+ years, taken them on and off many times. They were cast iron or cast steel, not sure which. A few years ago one broke an ear so I made a suitable copy from cold rolled steel. I have been scouring the interwebs for some more, and have had no luck. Attached is a SolidWorks model I made of what they look like. They are three identical pieces about 1" thick that fit together like this.......Has anyone seen anything like this?

Our local exhaust guy sells those. They're designed to go around an exhaust pipe that's already on a vehicle. I'll try to get more information.

Interesting. Does it take two of those per joint?

so what clamps those down on the pipe.

Yes it takes 6 pieces per pipe.

You put one set on each side of the collector joint.
