Because of how thick the pipes are now, the re-assembly process is a bit different now......just need to hang the pipe before hanging the motor in the frame. :mchappy:
Not wishing to piss on your chips but heat wrap sucks up water like a sponge and rots your headers in half the time.

Not sure if the silicone will save them... Never seen it tried.

I double-coated them with the silicone spray.....seems pretty damn water-tight.:thumbup1:

Right, I tackled this today. I've been spraying the nuts with penetrating oil two or three times a week for the last three weeks-ish. I was out in the garden and thought I'd just get a socket on the nut and see if they'd budge. To my surprise the first one I had a go at undid really easily as did another two BUT...

The inside nut on the right hand side as you look at the bike didn't quite go to plan. I think (hope :censored:) that it has unwound the stud along with the nut. This is what I'm faced with.

It's 33mm long, does anyone know if I've been lucky and got the whole stud out?

No idea about the length
 
It looks like a complete stud from the pic that you have provided, but you don't show the end that is "internal"; does that look like it has sheared?
Doesn't seem so in your pic which shows a rounded end to the stud at that face, just like the rusted end.

Hope that helps.

On further inspection I have removed the whole stud.

I've got a new one on order - I did think about replacing the lot but "If it ain't broke etc" plus four new nuts to hold on the new exhaust.

What's the deal with assembly? Copper grease on the stud going into the head plus copper grease the nuts?

Quite often the whole stud will come out with the nut welded on with rust, if that`s the case just buy new studs. Don`t go & re-use them even if you can get the nut off in a vice, just replace with new & smear some copperslip on as well for future.

Ive removed 20 odd in the last couple of years & on half of them the whole stud came out the head (nut seized on the stud) this is why its good to do it with a hot engine (head expands).

Here you go; no change from 3 weeks ago.
You have success so you are not quite believing it, yet??
