    Here is the info from Riva= Developed on our Dyno and tested extensively on the water, this water box features radiused exhaust tubes and end caps for optimum exhaust flow. Unique exhaust baffle will increase the low-end power and mid-range pull of your Yamaha watercraft. Delivers up to 15hp on modified engines along with significant torque gains. High-strength aluminum construction will survive backfires and meltdowns. Powder coated to prevent corrosion. A must for modified motors.********************

    My buddy has one in his FZR. Haven't see anyone post about real world gains but I can tell you one thing for sure... it is LOUD. The sound is fantastic, very good exhaust note, but LOUD.

    I have one also - installed since the first of July. Sounds really great - a distinctive low growl when paired w/ the Riva through hull exhaust. Honestly, I didn't achieve any top end gain but my ski did seem to gain some low end response. At the time of install I was on the stock limiter - so there may well be high speed gain that I couldn't achieve due to the rev limit.

    When you install, you'll find the stock rubber strap is about an inch too long to effectively secure the box. I tried to find a shorter replacement from another model ski without success.
    The actual fix turned out to be much simpler. Bring a saucepan of water to a boil, turn off the heat, coil up the stock strap, put it in the pan and let it soak until the water cools. Remove and lay the strap flat overnight. Next morning, perfect fit. Three months later, still tight.
