RIVA Racing offers a complete line of rear exhaust kits for Yamaha, Sea-Doo, and Kawasaki PWC. These kits will increase the horsepower of your machine, giving you an edge on the starting line. They will make your machine sound different, usually in a bad ass kind of way. You can listen to the difference in sound with these two installs provided by @jetski_pr (RXT-X 300) and @_bpych (GP1800). Check out the short clip on RIVA Racing Facebook page. Judge for yourself as to whether they sound weak, tough, or meh.
The RIVA rear exhaust kits deliver performance and cutting-edge style, while allowing for removal of the restrictive sound suppression system, located between the water box and hull exit. RIVA Racing rear exhaust kits also improve engine performance by reducing back pressure and restriction allowing for faster speeds.
All of their rear exhaust kits all include a powder coated mandrel bent aluminum exhaust tube, large billet, through-hull exhaust outlet, billet OEM exhaust outlet block-off, and silicone couplers built to withstand high temperatures. All of the necessary hardware for mounting and installation instructions are included.
The rear exhaust kits for Yamaha start at $359.95 with the highest price of $419.95. The Sea-Doo rear exhaust can be purchased a little cheaper depending on the model and year. RIVA Racing does offer free shipping on orders over $150 in the Continental USA. Also, shipping is delayed right now due to the demand. We have nothing better to do than sit home and stimulate the economy by ordering products online!
