    More power?
    Tuning required?

    What do you change ? You have to drill a hole in the hull of you Seadoo.
    Loud? Idling note sounds bad ass, don't notice it at WOT>
    More power? I could not tell a difference.
    Tuning required? No.

    Sound bad ass definitely. The only downfall is you have to remove the O.P.A.S. for some this is okay, for others they want to keep the OPAS. If you want to keep the opas get the Riva Free Flow Kit. Adds some balls to the ski. Better peroformance, louder, and easy to install.

    Yep, one of the clamps for the exhaust tip has to be tightened through the OPAS hole. You don't need the OPAS, get rid of them.
