Just to correct you on one point the bags on the F6 are exactly the same as the bags on the 2012+ Wing the shorter pipes question is not exclusive to the F6, the bags on the 2001-2010 are shorter now when the new bike came out all it seems most most manufacturers did was to just confirm the mounts and the fit and not worry on the length and just change the fitment guide to say 2012+.
I have the Rush pipes on my bike while the length is not ideal its more a aesthetic issue than heat and noise issue for me as such
The 2012+ bike is longer in the body than the earlier bike as I found out when it would not fit on my Stinger trailer
