snapped an exhaust stud

[BluprintZ]

When i rebuilt the Ducati Monster a few years back, i bought a rather expensive exhaust system for it and rather than replace the original flange nuts, one of the guys on the forum suggested i used brass nuts instead, seems that they were less likely to become seized to the stud, in fact he sent me a pack of four and they looked a lot better than the originals, plus of course they would never rust.
Eventually, i intend buying Motad stainless downpipes (the can is already a stainless Micron) and will probably replace the flange nuts with a brass set, as it will possibly stop any more of this snapped stud malarkey.
Anyone else used these?
