I very recently totaled out my 09 and purchased a 13.
according to totalmotorcyle.com there were a couple changes in 2011:
New for 2011
- Redesigned mufflers offer improved sound quality and feature a more tapered, classic look
- Improved and quieter shifting action via revised 1st gear ratio and taller teeth on the third and fourth gears
- Improved EFI settings that match the new muffler assemblies more accurately
- Refinished intake manifold is smoothed internally for improved fuel mixture flow
mine came to me with Vance&Hines pipes so I can't speak to the exhaust related stuff, but let me tell you what. THIS THING SHIFTS LIKE BUTTER.
My 2009 clunked LOUD from 1st to second, this 13 is smooth.
other than that I cannot tell any difference between the two
