    Like other responses so far ... thru-hull or free-flow will not yield performance gains, snapier throttle, etc....

    Loud - aka noise is one topic ... resonance (harmonic) is another topic. Both mods result in an awful brain-rattling nauseating resonance issue, but the free-flow is worse, due to the pump tunnel acting as somewhat as an trumpet amplifier of sorts.
    FWIW, I have a through-hull mod ... however, I still choose to employ a muffler device to address the resonance - and that has worked out well for me .... as I get the sound of a mod'ed ski, yet get to save my brain from turning into soup at 4-5K rpms.

    Air intake and ribbon delete will give a little better throttle response.

    Hello TimeBandit,

    Would you explain how you made the muffler to fit on your ski addressing the sound resonance? I would be interested to doing the same.

    What did you use for a muffler? I am used to load I raced street bikes years ago and would run open exhaust even on the street. But I understand how after awhile a little bit of dampening would be nice sometimes.
