Factory RS exhaust serial number check?

Hello all - I have a 999R with what I believe is a factory RS exhaust with a bit of a history (titanium and huge diameter bores etc). Does anyone know of a way to check the history of the serial number etched into the silencer or have any contacts that might be able to help with info?

thanks in advance

I would not know, I do not think there would be a record of exhaust numbers
