I'm swapping out the dual cat y-pipe in my Formula and I snapped one of the studs off in the manifold. Also one of the studs backed out of the manifold rather than letting the nut break free from the stud.

For the one that backed out I'm sure I can just run a new stud into the manifold, but does anyone have any ideas for fixing the other stud without removing the manifold from the car?

I've still gotta drop the tranny so I can replace the flexplate, so I really don't want to pull the manifolds if I can help it.

 

If you pull one at a time you should'nt have to pull the whole manafold if it's the intake. Exhast doesnt matter just pull it out and swap it.
