I'am with jocko

I think a set of tube headers, marine grade, of course, would help way more than just a tailpipe swap. CMI makes some, and there's a new company that boxes in the outer casing. I don't know if either makes a set for your application. Not cheap, by the way, might be more than the blue book on your boat.....
