Im picking up my 2013 in a few weeks guys and im thinking about which exhaust to get.I want a free flowing system and dual pipes(looks better on this beast than a single IMO).Its a pity Yoshimura dont make a DUAL R-77 full system.So im debating the Vance and Hines perf. headers with the R-77 or TRC slip ons.Has anyone tried this combination or similar?
