i have a set of OTT headers in my boat. its been real loud since i put them on. i figured thats just what it was supposed to be like. there a lil bit quieter with water going through but not much. with out water however they radiate temps close to the sun and it makes for an unpleasant trip. i want to keep the water but add mufflers or baffles or such to reduce the noise but keep the look. can i have both water and mufflers? i didnt know i wanted this until i recently went on a ride in a through transom header boat and realized i could hold a conversation without screaming and also my ears werent ringing for a half hour on the beach.
