Exhaust Blueing

[postnote]

I have noticed that my first exhaust outlet manifold is blueing, the middle and end are their original colour. Anyone have any ideas on this. My local dealership says there is nothing wrong although their demo has no blueing after 3000+ miles.

Depends how hard you ride and how hot the pipes get.

I find it hard to believe that any bike wouldn't have any bluing after 3000mi.
