broken exhaust studs
Any new or good ways to get out broken exhaust studs. I have drilled one out, but the hole is bigger at the start and I do not like this method much

Drilling out the broken stud *is* the usual method.
But to do this free-handed is asking for trouble. You need to make a jig to center your drill bit exactly over the stud. After drilling, you can retap and/or use a Helicoil or other threaded insert. For more info, do a search for "SSI Clinic", and see the tool that a pro used to deal with drilling out a stud. BTW.....Last week I removed my old heat exchangers as I was stripping the motor for the top-end work. Used the John Walker "Heat the living-$hit out of the nuts" method with my oxy-ace torch. NO broken studs, and they were *very* rusty. Thank you, John!

One way to remove a broken stud is with left handed drill bits.... sometimes the torque imparted by the cutting action of the drill can spin the broken piece out.....Craftsman, Snap-On, and Matco make left had drill sets...
You still have to get the bit centered...... and when installing the new studs anti sieze will be in order

If the final hole is a bit too big....you can use a stepped stud.
This is a stud that is say 12mm on one end and 10mm on the other. you just have to make sure the step is at or slightly below the parent metal level. Bob
