    Modding RXP Water box

    Hey guys got a question, I have read the HOW TO Thread on it. How short is too short when cutting down the back side of the waterbox, Is there a certain amount I should of shouldnt cut off. I see anywhere from 3-4in but is there any downfall to cutting it off that much. For right now the ski has only a intake on it but it wont be like this for long. I am a welder so this mod is only costing me my time thanks for the info

    Simple...

    Open end near outlets, sc side. Trim outlet flush inside. Then pop a single 5" hole in wall. Weld back up...that's the best flowing setup I have tested. Sound is deep and throaty.

    The Riva boxs are pretty short. Could measure the length of that and match it maybe.
