Trying to remove the exhaust stud

Tried to remove my broken exhaust stud this past weekend.

I first removed the lower side panels to get a little better access. Then I figured I had to remove a plastic shield that covers bottom part of the engine if I am ever to get a hold of that stud. This turned out to be somewhat notorious as the screws that hold it to the top part of the cover are hard to reach. Had to use a fine step offset ratchet screwdriver and it's was like $16.

The engine is made of aluminum, and the stud of steel. Steel expands less then aluminum and therefore the whole thing must be heated up before you can take the screw out. I ran for about five minutes on idle without my exhaust pipe. Figured the damage has already been done because I drove on this thing home with the exhaust pretty much disattached. There's soot on the inside of the engine exhaust, and I have no clue whether this is normal. Will see.

Anyways, as the thing wormed up a little, I just grabbed it with pliers and turned and failed miserably. It just wouldn't turn.

So this weekend I am all stocked up with vice grips, torch and fine set of drill bits just in case if I have to go nuclear on this thing. Wish me good like.
