Where the heck does that thing go, and what is it supposed to do? There's no description on R&D's site.

This is from R&Ds website.
The R&D GP 1300R Exhaust Power Sleeve will add a serious boost to low end and mid range horsepower and performance! The R&D Exhaust Power Sleeve installs between the exhaust chamber and the catalizer housing to increase sonic wave energy! The R&D Exhaust Power Sleeve will add the Y.P.V.S. (power valve) feel to the 2005 Yamaha’s non-power valved engine!

Soooo...does it take the place of a D plate? From R&D's description it sounds like it ("between the exhaust housing the the catalizer housing").

I've used gutted cat. works a little better "o" plate.that what it looks like to me,maybe different inside dim.

I dont think that this replaces the cat, looks more like an insert for the pipe a bit before the cat. R/D also has an "H20 Control Gasket" that supposedly shows gains by limiting extra water flow in the pipe.

Maybe it's a nozzle/diffuser of some kind... Maybe it restricts flow like an O-plate, except it does it with a lot less turbulence?

I think it acts to extend the length of the internal stinger of the pipe - WFO loaned me one to test - I will test it this summer - To be honest I am not that hopeful it will produce the promised results otherwise we would have heard good reviews by now
