Hello Mikey and welcome from VA. I have 23K miles on my 2014 R3T now and like the seat just fine. For summer though, I do put a Bead Rider on the seat to help keep the rear end cool.
I think swapping the TORs exhaust for the OEM pipes is a pretty good mod, I did that and appreciate the mellow sound, keeps me in good favor with the neighbors, and when I open them up, they seem to resonate just fine. The new tune that comes with them is quite a noticable bonus. Good luck
