Exhaust Clamp Question

[freerangequark]

I'm seeing some leaking coming from the exhaust clamp joints.

Can I repair/rework these parts? I thought that introducing curvature into the joint might work when the bolts tighten up and flatten it out, essentially preloaded. Or is there a way to properly seal them?

Is there a source for them other than $105 per half from AC Spruce?
