In another post the main EP3R post a lot of owners said some had speakers from factory but others didn't. They were debating whether it was manufacture installed or aftermarket and they concluded it was manufacture installed but ones without were taken out by previous owners to reduce weight.
I had lots of exhausts, 2.5 custom, RMO1A and TODA. All did the job in terms of improvement from stock. For a daily streeter with minimal or no mods I think the mid pipe is actually ok, change headers/cat and muffler and you'll free up most of the restrictions. RMO1A is not a quiet exhaust by any means, stick with OEM or Mugen if you want minimal sound. J's and Toda is my pick.
Intake, function = CAI, function and looks = GruppeM/J's and even Mugen.
Good luck in deciding :)
