    Hi gang
    What do you think of this kind of exhaust vs logs on a closed engine jet boat. Will they work well with jet boat plumming and are they worth the big investment?

    They flow better but look worse than polished logs. My buddy has a Glastron Carlson with a 460 and it has that style exhaust manifolds...

    I ran GIL BIG GUNS on my jet boat for any years, they were no wider than the original logs. I removed the dump hose, and used the manifolds to pre-heat, the engine, then dumped the engine water into the risers. Here is a picture of it from my buddies site.

    I got EMI's on my big boat (vdrive) and love them ,mine like sleekcrafters were the same width as the logs + or - ,they still however have some cam choice limitations ,depending on "tailpipes"/water entry ! Tom
