    Exhaust thru hull behind seat ? opinion

    I was thinking of doing something similar keeping the stock waterbox .... I searched the forums but found nothing..

    can the pipe go straight from the box up to the flange or those it have to have some sort of shape like a p trap or something

    Very very loud gets annoying after a while, and calls way too much attention to cops. No performance gains from it at all.

    All you need is to run a pipe from the waterbox out to the exit, nothing special. Ive seen a bunch of guys with it done with slow ass ski's its kind of funny to see them hit it and the jetski go no where lmao.
