Supertrap flow is in through the silver part and exit through the rubber boot. The Super trap lays where the waterbox went. The blue part points toward the front or bow. Put one 90* in end route hose back to exit side another 90* and out the exit. The Westcoast silencer can go inline anywhere after Supertrap. Water tap is the exit side of silencer. One note is look for auto radiator hoses with preformed 90* to eliminate connections.
