I acquired these in a trade. The mounting hole size and spacing is identical to our XS650s. They are made of aluminum.
Any info regarding what they came off of would be greatly appreciated.

Still looking for ideas on where these flanges came from...
They look a lot like the "big fin" header clamps I have for the "Dragon". Suitable for use on 1-3/4" TT pipes (no welded tabs, the clamps easily slide on from the outlet end.) The TT pipes have a long stepped/swaged section (large diameter, no obstructions) that closely fits into the exhaust port, and the clamps press on the expanded shoulder of the swage. Getting a good gasket seal is important since only the edge of the pipe presses against the outer edge of the gasket, there's no flange in there.
A desirable clamp back then.
The mystery in your pic is the shadow ring from something pressing against the backside of the clamps. On mine, there's nothing in there to make those impressions. The ID corner edge of the clamps press on the header swage, like the shiny inner edges in your 2nd pic, nothing else.
Maybe someone machined down and thinned some stock clamps to use as adapters for 1-1/2" pipes. And those were pressed on by the "big fin" clamps...
