Removing Threaded Studs From O2 Housing

[Gunter]

Most of you probably haven't had to remove these but they are the threaded studs (bolts without heads) that are screwed into the O2 Housing on one side and connected with a bolt to the downpipe. When i was removing the nuts from them i couldn't get them off so i decided to cut them off with a dremel. So eventually it worked but in the process i pretty much mangled the studs. So I don't know hwo to remove them since they have no head or anything. I've asked friends and stuff but no one has any ideas. I suspect there must be a trick to this so hopefully someone has it.

Double up the nuts on the stud then loosen (clockwise) the bottom of the two nut. To install the stud, tighten the top nut (counter clockwise). Or reverse... I always forget which way.

Try looking here. This is for mani studs, but the same method works for the O2 housing studs.
