I got a pair of "Chevy605's" just in case I get cited for my D&D's here and Denver and they make me go back to "stock pipes." Slipped them on and rode around one day, wasn't real thrilled, but then 1) I'm used to D&D's, and 2)there's still a lot more that could be taken out of the pipes. And, like Ian, I think they'll be a good start when I want to start figurin' out for myself how to get baffles out/ drill them etc.
