    Had mine apart the other day, but don't know the diameter.......why do you need to know the size? It's a simple job to take apart & measure.

    Looking to homebrew a Free Flow Exhaust. Finances dont allow for the RIVA part at the moment and I dont trust the PVC to take the heat of the exhaust and definitely cant afford my ski sinking on me. I have the 04' Hull and am currently having my drain plugs relocated to the rear of the ski, so the ski is not at my residence for convenient measuring.

    My plans are to grab a stainless pipe, mandrel bend it 90o degrees and use that as my free flow, install it when I go to pick up my ski from the drain plug mod. If that is too expensive, then I wonder how a painted galvanized pipe will hold up?
