    How tight should the nut holding the exhaust header pipe onto the cylinder be? I tightened as tight as I dare (I had to replace one stud already). I used a stubby open end wrench, so I didn't have a ton of torque on it. Does anybody know the spec if there is one?

    7.2 ft/lbs (a hair over finger tight). Be sure to use plenty of anti-seize lube.

    Thanks. I used the anti-seize. The PO must have as well because all it took to remove the broken stud was a little pressure with some vice grips.
