Linky no worky. ;-} As lean as this bike seems bone stock in the low revs, I can't imagine any slip-on improving power across the board without some flavor of piggyback ECM. You might pick up 5 - 7 up high, but I bet down low will just suck without a Power Commander or some such. I love the look of the carbon muffler cover. Part of me wants a little extra noise (slip-on), but by the time you add a fuel management system to make it right, it just got real expensive.
Probably not, but they might have Power Commander stickers that make other dudes think you really have one. Try Pep Boys too.
