the problem is where the y pipe connects to the sock manifolds... i snapped one of the 3 bolts off. how are these studs in there? i have torches, so if all i have to do is heat and use a stud remover that wound be great. its all stock and OEM. also would i just go to the dealer for new gm studs?

 

I believe the studs are screwed in. Your best bet is to drill out the old stud, then just use a long bolt and nut to replace it.
