Another option, is to drill it out, get one of those studs that is larger on one side and tap new threads for the larger side.

 

That's true. I was going to try to remove the exhaust stud by putting two nuts on the same stud and then try spinning the first nut

with an open end wrench.

 

not the real picture but demonstrates what I'm talking about

 

 

Photo seems to indicate not broken flush with manifold. That should be a breeze to remove.

I realize these pics are not your manifold, but your post did say it was flush with the hole, so we took it at its face value. Now if there is enough thread showing to get 2 nuts on it, that would be the proper way. I have also gotten a slightly larger nut and welded it to the stud stub sticking out, but the only way it would come out was heating the area around the stud to cherry red, and make sure you do not heat up the stud itself, otherwise it will just break where you got it almost to the melting point. Heating it up will expand the metal around the stud making it easier to unscrew. The manifold will expand faster than the stud.

 

yeah my bad, once i completely remove the y pipe i will have some space to work with. When the rest of the exhaust is installed the bolt is flush. not sure how much space I will have though.

 

i'll try the trick with two nuts on the stud and if i don't have enough stud to work with i'll just double up on gaskets and go with out one bolt.

 

I wish you luck either way, we had a bad leak, and we had 2 broken. If you have to double up on gaskets, get some of that copper spray sealer, it is very very sticky and should help sealing it.
Keep us informed of your progress and outcome.

 

ok i will i also post pictures of the finished product. thank you guys so much for your help and have a great night
