I bit the bullet
Broke down and ordered Hogslayers (polished) and a Triumph filter today. I'll be out of town for about three weeks and dealer says he'll have them when I get back.
My bike's production date is 1-27-2010, and thanks to the pics Dazco posted, I know I have the secondary SFI. I'll have to look up the right tune when I have them installed. I also had the dealer set aside a couple of exhaust gaskets even though the install video says they're re-usable.
This forum has been a great resource for me; as an example I learned about the SFI, proper tunes, chance of gaskets getting messed up when changing exhausts - all right here. Thanks guys - ya'll (NC for all-of-you...) have been really helpful!
