Snapped exhaust stud

[His Dudeness]

Not sure that rivet nut is the solution. I plan on getting the old stud out in tact, thus still having decent thread to install a new replacement nut. Just looking for suggestions of how to get the stud out.

I bet you planned on getting the nut off without snapping the stud too! Deadeye had some success with an impact and a stud extractor. That's probably the way to go.
