No, no, my friend headers turned gold after few days and so did mine. And that's obvioulsy ok, 'cause I knew in advance they would have turned gold (which I like).
The problem is that my headers showed after a few days dark brown surface
stains over the golden color (shown in the pictures I attached at the beginning of the thread) which my friend headers never showed. Just that.
I received a pm from Johnny6035 who has my same headers and exhaust (by the way he also has a gorgeous bike!). Here what he told me:
Hi Daniele
I've had a similar problem but nowhere near as bad as yours. I use Autosol cream metal polish on a felt polishing bobbin, fitted in my cordless drill, to shine them back up. It only takes a few minutes. I think the main problem is with surface discolouration rather than pitting. Stainless steel contains quite a lot of carbon and other compounds such as arsenic. When it is heated - like an exhaust pipe - these compounds can leave residues on the surface. Combined with rain water this discoloration looks terrible. Rather than wear your fingers out polishing, get yourself some polishing bobbins and a drill.
Good luck Johnny
I can obviously accept some dark stains (which have nothing to do with the headers turning gold) on the headers due to normal use but I think mine are really too bad...and after just a few days.
Now I polished them and made the
magnet test...well...results are a little bit weird because somewhere the magnet sticks on the header surface and somewhere else it does not. Same thing happens on the exhaust. However, where it sticks on the header it is not so strong like when it sticks on the frame, for example.
And finally some photos for those who asked!
