Exhaust gasket blew, and exhaust studs ruined

You have the aluminum gasket ? I have that also and could never get it to seal right. I traced mine out on 2 thin pieces of cereal box cardboard, cut them out and used some Permatex anaerobic gasket maker to seal them to both sides of the aluminum gasket. Been on there and sealed for 6+ months. "Permatex Anaerobic gasket maker" is a motorized bike builders best friend. Its expensive but worth every penny. I use it on everything that needs sealing. Carb , head gasket , exhaust gasket , petcock , intake , etc. This stuff.

I always use Vise Grips to back out studs. Just lock them on as close to the engine as you can. ! Gently back them out ! You can replace them with regular bolts just take the studs to the hardware store with you and get some Allen head bolts the same size but half the length of the stud part that goes into the engine. You want to make sure they are not too long cause if they bottom out in the stud hole and you crank on them your going to break something.

I use Lowe's, and Home Depot as they are close to me. They have bolts that are threaded to the top. You can get a couple and either cut the head off or grind the head off, also buy locking nuts. I use studs, and put double nuts on them, first a regular nut followed by a locking nut...both a Grade 8.8 metric (USS Grade 5)

I don't have a grinder, here's an idea. Can I just buy a couple of bolts, not too long, and just bolt the exhaust into where the studs used to be?
