    FREE-FLOW utilizes the OEM exhaust outlet, and removes the resonator. Cheap upgrade for throaty sound...NOT MUCH in gain of performance unless the waterbox is modified...Its nice and loud, but the resonating sound from 2500-4000rpm is annoying...

    Thru-Hull is just what is says, a thru hull exhaust requiring a hole be cut in the rear of the ski. This eliminates the resonating effect of the free-flow, and provides the same performance unless combines with a modifed waterbox, Green/Riva box, or a Gibson exhaust....

    Very well said Danny, right on the money.
    I have to agee as i have run about all you can in exhaust and thru hull is by far the best upgrade for exhaust. It creates much more room in hull and you can choose many different options per wanted sound.

    Do you need the waterbox?

    Can you use the stock plastic thru hull piece instead of a metal one? Relocate it to the rear and block the factory hole?

    I took these yesterday when i finished the Free Flow install on my RxP-X. Its not as loud as I thought it would be. It's got a growl to it now, and sound 10x's better than stock.

    you replace this

    with this
