When they cut the cats they could of josseled one of the upstream o2s loose slightly...when you idle where does the tach sit...right at 700 is normal for a stock.sixxer

a bit high...clean your MAF, IAC, and TB and see if it helps...this idle issue could all be a coincedence
i will try this and let you know what happens!

How do you idle a auto on the highway?
what I mean by that is that the RPMs are higher when I let off the gas at 60 then they were before i got the exhaust put on. For example, before the exhaust when i got to 60 and let off the gas it would go down to roughly 1600 RPMs but now with the exhaust and i let off and it's stuck around 2100 RPMs, does that make sense?
