    Mystery Box in back of ski??

    Theres a what looks like to be some kind of resonator its right after the waterbox but after the box that i dont know is the resonator.. What is that? from some more room i was thinking about removing it, but removing the box make it any louder or do anything to the engine (since two strokes are all exhaust). Ski is a 2001 rx.

    Yes it is a resonator that reduces noise from the exhaust. It has no effect on performance with or without it .I leave them in to keep the noise down, must be a mature age thing !!!

    I removed mine & quite enjoy the brap!
    This is a direct replacement hose & hull fitting from a 1998 XP Limited that by-passes the resonator.

    By removing this resonator/silencer it will sound a bit louder. But if you're looking for your ski to sound louder look for an after market water box or have yours gutted.
