RIVA Free Flow Exhaust Kit Yamaha 4-Stroke Superjet

Description

The RIVA Free Flow Exhaust Kit for the new Yamaha 4-Stroke Superjet replaces the restrictive sound suppression system located between the waterbox and hull exit of the SuperJet using a high-temperature silicone hose. This reduces back pressure and delivers an awesome exhaust tone.  An added benefit is how it cleans up your engine compartment with the removal of original bulky plastic components.
