IMHO take it to a pro...peace of mind getting it out...this will be alot cheaper than if you do more damage to the head...I admire people that do their own work but if you never have extracted a broken stud, better err on the side of caution..
I would weld a nut to the top of the stud with the help of the heat of the welding the nut and also when it is hot take a candle and melt some wax on the thread. it helps when you back out the broken off stud
+1 on the ez outs. I have found that the snap on ones are the best. I have tried the cheap ones and they break, and just make more work for you. If you try it yourself, buy a good quality set.
i had a stud break as well. i tried the easy out route, and gave up on that when i could tell that if i twisted it any harder, it would break off.
took it to a local indy. he had this tool by jims, you put it on over the exhaust studs and tighten it down with the remaining nut. it then acts as a guide for you to drill the broken stud out. once you drill through, you take the jig off, and you can grab the threads and just pull them out of the hole.... it was awesome. head didn't even need to come off.
cost me $100 bucks, but it was worth it not to screw it up more, and i looked, the jims tool is $89. thought about adding it to my toolbox, but hopefully, won't have this situation again.
Thanks to all for the advice and positive support. Think I may leave this to a pro. I'll get plenty of satisfaction putting the new exhaust on. Ride like your life depends on it!
Have had similar probems and use the EZ-Outs with good success. Like a previous poster said, make sure EZ-Outs are of good quality, take your time and progress from a smaller bit to larger bit and stay away from the threads. I used Craftsman from Sears but Snap-Ons would be a good choice as well. Stay away from the cheap Chinese ones.
chill out ! there r a couple of way to fix this 1 IF? u can drill it out an get an easy out in there to remove it 2 take a center punch and a small ball pean hammer an try to walk it out by tapping around the outer edge of the stud,this usually works.
use some never seize when installing new stud
