I think that Paul & Rachel had this done on EVILMOG and seem to remember that they had some issues with the coating coming off. I'm not sure whether this was resolved to their satisfaction. Why not send 'Pitfield' a PM for an update.
Peter Brown has also had some issues with his ceramic coated pipes, I believe sometimes it takes a few goes to get the coating to stick properly..
I had mine titanium wrapped by Krazy Horse and they look good after 7k miles
