I agree with Tony, in this case dremmel cutting the top 1mm slice off the casting to remove the corroded section is the solution that will have the highest probability of working and requires the least special tools and expert operation.
the key is to cut the casting away but dont cut through the stud, it will be required to touch the edge of the stud to remove all the corroded material, but then stop.
I am sure some one will remember the thread that had the pictures of what was done when one of the others came up with this solution

Re: HELP!!!!!!....MkII
Would you be able to get the pressure to hold the exhaust at the equivalent torque ?

For those of us that remove the pipes fairly often, this sort of fixing might be a better alternative:

Big V your second picture is exactly what i looking at, the stud has snapped in exactly the same place and i agree with who ever said that spraying it just aint gunna do a thing as its sealed tight. I realy am stuck at the mo as i dont wanna rush it and make things worse. But thanks again guys for all your thoughts and opinions

According to the spec sheet, you could generate almost 1800 lbs of clamping force...... enough?BigVeeGrin wrote:Would you be able to get the pressure to hold the exhaust at the equivalent torque ?

Hell, yeah.
That's on an 8mm stud, but easy enough to wind in an M8 bolt with some locking compound until it seats, then cut the head off.
that'll give you a stud that won't
a, seize, and
b, break.
You might have to take several bites if you fit a new compressible copper seal, though, as it deforms and you'd need to take another go or two.
It's not falling off, it's an upgrade opportunity.
