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

    From Talking to Art at jetworks yesterday he believes it goes between the stinger outlet piece and the stinger. He says they had a similar item for the super jets or SXR's.

    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 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

    I just think that people havent tried this and the H20 control mod cuz they dont trust R/D's claims.
    Is your ski a non-PV 1300?
