Slip a nut over the end of the stud and weld the nut to the stud. It
doesn't matter that if there is a 5mm or so gap, a wire-feed welder will
fill that right up. After it cools, it'll come right out but you will
probably need to helicoil the hole.
Some folks like brass nuts on exhaust studs to prevent this problem.
However I like to use stainless steel nuts on exhaust studs. I still
use anti-seize compound with them and I've never had a set stick.
