So in the process of doing the driftmotion upgrade, i stripped the threads on 2 of the studs with my stud remover. there not budging. any ideas?
Removing exhaust studs

Drill them out. Use one of the studs that came out to measure how deep you need to go and mark your bit accordingly.
I assume you've tried vise grips? It really shouldn't be that hard to un-thread the studs from the head.
If they're in that tight they didn't really need to be changed so it's more of a sidegrade than an upgrade 
How exactly are you trying to remove them? Tried two nuts? Loosening by the rear one? Even after mine were stripped, loosening them still pulled them out slowly.
Its aluminum, you must be doing something wrong... But just cause they are screwed in tight/stripped doesn't mean they wont pull strait out when you go to torque them down.
First coat the studs around four or five times at where it meets the head with pb blaster. That stuff works wonders, as its a catalyst. Give it time to sit between each coat, and try the double nut method as its easier in a tight space with the engine in the car.
The top of a exhaust stud is formed like a 6pt hex. A 1/4 socket wrench & 6mm socket fits perfectly on it and takes them out easily (unless u got the flat top studs, then your screwed*).

I have a similar problem with a spare head I am doing up.
One of the studs is broken inside the head.
Tried drilling it but thats useless as its hardened too much.
Went through three good quality bits & just scratched the surface.
Using a stud remover is also hopeless as you cannot get it to bite into the hard material.
The only other way I could think of is to weld another bolt to it & remove it that way, pity I dont have a welder.

is such a tool made, or is it a case of just taking the head to a machine shop with EDM capabilities?
(had some EDM stuff done for me last week here at work and damn, you can machine some pretty tiny features with it)
A few of the better shops here have a small Sinker setup for broken bolt removal Adam not sure how common they are or the costs involved in buying one though. (always seen it as a last resort thing you know for whn you break off an extractor in an expensive part)
