Riva RY1620 is a free flow exhaust kit designed for Yamaha 00" GP1200R WaveRunner. It is made from aluminum and includes a crossover tube, rubber exhaust hose, and necessary hardware. The kit is intended for competition use only and is not covered by the Yamaha limited warranty.

The kit can be difficult to install and should be done by a performance watercraft shop if you do not have the technical experience. Once installed, the kit can improve the performance of your WaveRunner by reducing exhaust backpressure and increasing airflow. This can lead to increased power, speed, and acceleration.
