chain cover and other questions

[baxtercat_imp]

Hello People. New to the forum--just purchased a 2013 ABS with 5 miles on the clock. I'd like to make a few mods right away, and could use your collective wisdom. So...

1. the chair cover on the left side of the 2103--just behind crankcase/stator over--is black plastic. In pictures of the 2104 and DLX model this appears to be raw aluminum, not plastic. Is it, and are the parts interchangeable?
2. the OEM Honda accessory chrome covers for the instruments look nice. are they chromed steel or chromed plastic?
3. not such a fan of the steel headers. Does anyone make a double-walled chromed-steel replacement for the 2013 4-into-1?

Sorry if this information is posted elsewhere--my searches didn't produce it.

Thanks for any help.
