Justin that was a great detailed post illustrating how simple the install is on the High Flow Sportcats with X-Pipe. I'm sure she sounds like a beast
The majority of X-Pipes which have been shipped/installed in the last two weeks have the resonators installed because of the combination of either a Remus or Eisenmann muffler. Without the resonators it has a very loud rasp which can be an annoyance at certain RPM's.
