eh good luck. if you just broke one stud and the rest are solid and on it shouldn't give you any problems. Taking my manifold off took 30 minutes and a hell of alota cussing on the two bigger end studs...along with alota double nutting and muscle. None of my studs broke though so I didn't have that problem. I replaced mine with alota anti-sieze and the Hahn s16g install kit SS studs tho.

If it broke w/ thread on the outside, use some really good and really long pliars


If it broke w/ no thread on the outside, use a drill with a bit smaller than the stud and a EZ out (can be bought at Lowes/Hardware Store) and put the ez out in the hole u drilled and rip that puppy out...or do like I did on my oil pump housing and drill holes into the broken stud and hope that it crumbles and take a vacuum cleaner to it to suck up the broken metal.
