    I was looking at both kits r d uses a ridgid pipe which to me looks better than just a hose
    just my two cents worth im not in a hurry so its no big deal to me .
    Im on a project right now doing a 1100 conversion in my stand up, so i have time

    I will keep you guys posted, we are gutting and shortening the waterbox, bypassing the resonator and building a aluminum thru hull. We have a in house CNC machine so we are eager to get our hands on the new Spark.

    I done the same thing to all my skis, I build my own thru hull exhaust. On the waterbox I split it, gut it and add an impact plate where the hot gasses come in, then I slice a few inches to shorten it and weld it back up.

    Here is the one for my 2012 rxpx, the welds are shitty on this one but no leaks, I welded it after working 16 long hours on a friday night, trying to piece it together for the weekend.

    I come from modding subarus and have no idea about sea doo's in any sense. But I know with cars if you change the exhaust or the intake that the motor needs to be tuned for such mods since allowing for more free flowing air causes the stock tune to the run lean. is this not an issue with sea doos?
