$360 all stainless
$405 carbon end cap, stainless body
$513 all carbon

Also available as a full system

Look past what these people are doing to what may very well be an engine that's not even broken-in yet, but wow that sound!

That is a Yoshimura R-77D full system on a 600 (no collector/cat), so it is a lot louder that a slip on. It does sound good though. I think it might be because the two exit tubes are different sizes (diameter and length), so two different notes are resonating at the same time. The R-77D muffler looks shorter, and the connector pipe looks longer than the R-77, so that it ends just as far back. A conical shaped shorty with the same dual exit pipes would be nice as a slip-on (retaining the collector/cat).

So, by getting a full system, like the R-77D, it would have to be taken to a tech and tunned? [assuming myself with no tuning tech/experience]
