    I have a modified primary water box from R-Rated. It didn't give me much of an increase on top end but it did give me a noticeable gain in midrange.
    You can get the "U" pipe from R-Rated much cheaper ($79.00) than the exhaust from Riva. It does the same thing and you don't have to cut the outlet pipe that goes through the back of the hull like you do on the Riva.
