If you're like us and can't
stand the ugly sight of those black rubber Salisbury style flappers then
feast your eyes on this piece. Hardin Marine has handcrafted these
beautifully polished stainless steel exhaust flappers to eliminate that
eyesore. The flappers feature and O-ring seal to eliminate the
possibility of any noise from the flapper during normal operation.
This new flapper represents the ultimate finishing touch to your boats
exhaust system. Available in 4", 4-1/2" or 5" sizes.
