Exhaust How Do I remove the engine exhaust studs?

[StrontiumEthics]

There are 2 studs that comes with on the engine to mount your exhaust, how do I remove them to put a bolt instead. I tryed using vicegrip but it doesnt budge. Its a pain b/c I got an expansion chamber and I gotta use bolts instead of studs.

2 nuts(or more) locked together on the stud & undoe what way.If it's a really hard stud put it in a vice as low down on the stud as possible(be carefull not to snap the stud at engine level or your in deep poo)

If they were installed with Loctite you may have to heat the stud with a propane torch then use your visegrips to back them out. That is if you don't care about ruining the threads. Just heat then twist you may have to do it a few times so you don't have to twist so hard as to snap one off.
