Just checking size of studs/nut are M8 x 1.25mm thread on a curvy and would brass nuts be better choice than stainless?

When you've cut right through and removed a section of the nut, using a suitable rod as a drift tap the nut - and I mean tap, don't lean on it any harder than you need to - in the direction required to undo it, it won't be gripping the stud very hard anymore, and a little tap should see it start to move.

I really mean this - don't try to undo exhaust nuts that are even stiff to turn, cut them off. The various threads on here detailing how trying to undo the nuts attest to how easy it is to break the studs, and what a pain it is if you do.
I've never broken an exhaust stud and I've been required to remove some really rusty crud in the past - this works.

I'd to what Sid specced, I'm able to get mine off with a 6 side socket (and penetrating oil) and they're siezed.
4 stainless steel nuts are £8 on Westgate Rd, the studs are a few quid each

£8 are you f***ing kidding?
