What year bike? I have heard that on the '15's you can go with the cat. eliminator pipe/Stock muffler set-up and gain some sound as a lot of the sound is reduced by the massive catalytic converter. I kinda wish I would have went this route vs. the Graves 3/4 system. I actually like the look of the stock muffler on these bikes but was just too quiet. I pulled the trigger in an aftermarket 3/4 system before doing my research...
A&R race baffles seem to be the go to, look em up!
