    GPR RIVA Free Flow question?

    Why is the Riva free flow different between 1200 and 1300 GPR? The water box has the same size outlet, and the silencer is the same in and out, is there a difference on the exhaust outlet thru the hull?
    The one piece hose 1300 one looks like a better and possibly quieter choice if they both would fit.

    Not sure if there is a difference. But I think the 1300 blue FF hose is the best. If your going to run the FF put a 1200 water box in with it. Or just run the stock 1300 box and sound suppression. Just my opinion.

    Disregard this question. I have found that the exhaust exit has the same part number, and know the waterbox has the same outlet as I installed a 1300 waterbox on my 1200 to help quiet it down. It does work noticeably.
