I don't know about Vulcum but Sikaflex-221 has pretty good heat characteristics: up to 355 degrees for 1 hour and 320 for 4 hours constant.(See attached PDF) How hot do you think that the exhaust gets?
I bought some Vulcum after using up my first tube of Sikaflex-221 and didn't like it as much. It seemed to dry a lot slower and didn't have as much initial tack.
Now I'm using Sikaflex 295 on my windows where the weather stripping has hardened and it's working really well.
Good luck,
