PowerFactor Exhaust Kit with Power Box

Wake up your big displacement motor with this complete kit!

The ultimate freestyle exhaust system. Designed for flat water freestyle and free ride, the PFP exhaust optimizes the power band of most modified jet ski engines. The exhaust manifold bolts up to any Yamaha 701 exhaust bolt pattern. The PowerFactor dry exhaust, is designed so nothing interferes with the engines top end. This allows for any combination of top ends (Bore, Stroke, and Exhaust Valves, etc). It also allows easy access to engine components.
