I am surprised to hear that people have bent the exhaust down-pipe/header flanges on the fixing collars, the studs are only 6mm threads how the hell do you bend a 6mm thick stainless steel flange with two 6mm threaded nuts? I would have thought that they would shear off before bending the flanges on the collars.
if you replace the studs use Stainless steel replacements and give them a dose of Copper Slip before putting the nuts on.
I remove the nuts from the studs each year or year and a half and re Copper Slip them, do them one header at a time that way the seals stay put as do the headers.
After the initial quarter undo turn I can remove the nuts with my fingers.
For aesthetics put a domed stainless steel nut on top of the manifold nut if also acts as a pinch nut, I have never in 3 years had one come undone
