    Does anyone know what the inlet and outlet outside dimensions are for the stock waterbox on a 99 GP 1200?

    Thanks!!

    waterbox

    3-5/8" O.D......Your trim tabs shipped out Thursday. United States Postal Service. I put the declared value you wanted on the customs form. Let me know when you receive them.

    Both inlet and outlet are 3-5/8 OD?

    Thanks for the shipping update Mike.

    I'm not positive on the inlet, because the box I measured from was a prototype for triple pipes. Does your box have the same size inlet and outlet? I've got a stock 800 box that has smaller inlet and outlet.

    I got an 800 that has a 3-5/8 outlet but the inlet is only 2-5/8. So I think I need to get the 1200 waterbox.
