| Karl,
Pre-2004 all 749/999 (including the R) swing arms were finished in a grey cast finish. It was only in 2004 that R's gained the black paint fabricated aluminium swingarm.
For 2005, I think the fabricated swingarm is standard across the whole 749/999 range (but, don't quote me on it).
Sorry, can't help you with the exhaust question.
Cheers!
