There is nothing different about the R mechanically. Read up in the other forums for all sorts of reviews, dynos etc...
I run a AAM muffler: no drone, but some nice V6 growl. Could be a tad louder for my tastes. I already had a Nismo and the H pipe else given some seat time with other full bolt ons I may have gone another direction. I personally don't feel any need for an intake on the Z.
This is purely for sounds and aural enjoyment: the 5-10 HP gain is up top and only seen on a dyno. 300+ HP is plenty :P
