RIVA Yamaha GP1800 Free Flow Exhaust Kit

Replaces the restrictive sound suppression system located between the waterbox and hull exit on your watercraft improving engine performance by reducing back pressure and harmful detonation. Made from mandrel bent aluminum tubing, bead rolled on the ends to secure couplers, and powder coated to prevent corrosion. Includes high temp silicone replacement coupler and installation instructions.

Fits all GP1800, 2016 & newer VX, and VXR/VXS models equipped with 1.8L engines.
