    RIVA water boxes available for pre order

    If you would like one of these water boxes please pre order now. I won't bill your card until it's ready to ship.

    I don't have an exact ETA yet but these are coming very soon.


    07 and older water box
    $359.95

    Our Pro-Series Sea-Doo Water Boxes deliver increased horsepower and performance by reducing exhaust restriction and back pressure. Developed on a flow bench, our water boxes feature radiused exhaust tubes and end caps for optimum exhaust flow. Innovative short design allows easy servicing of supercharger without removal of exhaust system. High strength aluminum construction & precision welds will survive backfires & overheating. Powder coated to prevent corrosion. Includes detailed installation instructions. Note: Requires use of RIVA Rear Exhaust Outlet Kit (part# RS15050-ET). Will directly replace and upgrade RIVA Rear Exhaust Kit (part# RS15050-1) utilizing existing rear exhaust outlet installation.

    Cool

    Hopefully Danny can get these and do some flow testing to compare results like he's done in the past with other waterbox's.

    It will sound just like this (same design)





    Danny already did flow work on my shorty water box so these results will be similar but better as this box has spun ends and a mandrel bent exit pipe.

    They are like the GH boxes right? No baffles?

    Why don't they sell a complete kit with the exhaust tip?
