Ultra sanitary and absolutely necessary for the stand up freestyle and freeride SXR purist. Allows exhaust pressure during nose stands and aerial moves to exit out the side of the ski, instead of loading up the rear exhaust and engine. Limits your intake grate area from ingesting aerated pump water from your rear exhaust during tail stands and other aggressive maneuvers. Salt water durable kit includes all stainless and billet aluminum parts, all pre-bent and fitted hoses, custom made aluminum splitter, stainless clamps and polished aluminum exhaust outlet with 90 degree elbow.
