they make this exhaust putty, kinda like JB weld... Ya can find it at auto parts. I bought some once, to fix my exhaust manifold, it said it was good for like 2000 degrees or something. Might work for your needs. It was like $6... I didn't have to use it. Ended up finding another manifold.

JB Weld is not rated for exhaust parts, but only for 500 degrees.

 

It is superb for carburetor parts though. Fixing threads, and all sorts of metal stuff. The only failure I ever had with it,

I tried it on a plastic radiator tank, let it cure the required hours, but it leaked as soon as the pressure built.
