I pretty much concur with the Ferret on this one. My 2013 came with a full Yoshimura exhaust thanks to the original owner. Out of curiosity I found a factory Yosh dyno compare, on their site I believe, showing a 5 hp gain at the top end with no other mods. The torque was about the same, as was hp til about 5k when it gradually gained to peak.
I really didn't care much about it either way as 98% or more of my riding is below 5k.
With a cam swap and Guhl flash, I improved peak hp, and more usefully for my purposes got a nice little torque bump at lower rpm.
Good Luck,
Ben
