I have a V&H short shot staggered for a 09 Nightster. Looking to trade for a 2:1 that will fit my 09 nightster.

Just FYI..more than likely anyone who has a 2:1 set-up isn't gonna wanna go backwards.
There's a slim chance someone may have bought their bike with a 2:1 on it and wanna get rid of it, but you'd more than likely be better off selling your short shots and buying a 2:1 from someone (here, classifieds, craigslist, ebay, etc.) with the cash.
(or buying a set and then selling yours to recoup the cost)
Good luck with your quest.
