This modification utilizes the stock exhaust system and flame arrestor case. Original air filter element is replaced with RIVA FX Power FilterŪ providing increased airflow to throttle bodies allowing the engine to produce more power.

RIVA FX Velocity Stack Kit is installed. Kit replaces restrictive factory stacks delivering improved throttle response and top-speed. Installs easily and locks into place on throttle bodies with provided set-screws.

RIVA FX Free Flow Exhaust Kit is installed. Kit replaces restrictive sound suppression system located between waterbox and hull exit reducing backpressure and engine operating temperatures.

RIVA / Solas Concord Impeller is installed (see listing above). This impeller was specifically designed for the FX to provide increased acceleration and top-speed. RIVA Billet Impeller Cone is included.

RIVA FX Performance Ride Plate and Top-Loader Intake Grate are installed. Our ride plate and intake grate combo increase top speed and reduce cavitation. Handling characteristics are significantly enhanced including the elimination of low speed hunting.
