    Use this tip and buy matching size pipes, elbows, and clamps from Frozenboost.com to make your own and will end up costing less.

    So I just have to buy this tip kit and free flow exhaust to get my FXSHO to have "Riva Rear Free Flow Setup"?

    No. Frozenboost.com is a website that many use on here to make custom intakes and exhaust, including me. You would buy some 3.5 in pipe, (45*, straights, and what ever else you need) some 3.5 in Silicone elbows in straights, 90*,45* and 3.5 clamps avs whatever else you need to go from your waterbox to the tip I referenced.

    Here is an example of items from Frozenboost.com that I used to make my own intake. Browse around and get measurements from you ski of were you would like to put your exhaust exit as this would be a one off exhaust that you create.

    Um maybe I will do DIY with that website for cheaper! Thanks for sharing! How your VXR running? I will buy a VXR in future to get away with Supercharged FXSHO!

    You will need a whole saw that is 3 3/4 in I believe. The instruction will tell you in the tip from Riva racing


    Also in the exhaust image you can see how it routes up high then back down? I would do something similar so archimedes principles of boyouncy can be of help when the Ski is not running on the water (Lake, river, ocean). I hope this makes sense.

    I wouldn't know exactly what you need, but these parts can definitely do the job. They might require some cutting and finagling
