Copper slip on Exhaust Studs?

[Billy Balthorpe]

When ive done the "shearing the studs" thing in the past ive replaced them with stainless studs and stainless nuts (dead cheap from FWB in Stoke). Then put another nut on the exposed thread and locked it to the first one so there is no bare thread showing, all covered in lovely copaslip of course. On all the bikes ive done this job on, my Blade was the only one I had the good fortune to remove the exhaust again, and it came off with no drama, and the full Ti/carbon Akrapovic went on and sounded lovely.
