    I run the Riva Blue silicone tube replaces everything best way to go in my opinion. They advertise it for 1300 but it works perfect on the 1200's too.
    I would not run the PVC!!!!! I know some who have for years and never had an issue, but others on this forum have sunk their ski running them. Go aluminum or Riva tube IMHO.

    Especially running the Jetworks valve AND riding in "no wake zones" with the plastic.I dont have no wake zones and have used ABS pipe without a problem at all.Last year i switched over to the Riva stainless tubes,just to be on the safe side.

    I'm running aluminum and never had any problems with it. It is thick walled aluminum pipe, sounds pretty good and not too loud. Yet still gets everyones attention

    PVC on one boat and the Blue tube on the other. No problems with the PVC at all.

    I run a PVC tube that I made so I would not have to cut the hoses.

    My thoughts are it is smooth but holds "SOME BACK Presure" at high RPMS. No facts of any kind to back it up. But JMO
