At WOT the turn down are above water sot here is no restriction.

Check out fish the classi for lots of ideas on making yours managable.
A lot of people end of putting sound deadoning inside the engine cover as well.

What is fish the classi? I like the idea of low backpressure that equals HP and fuel economy. Can you post some pictures of your set up? I would like quiet too. Thanks, Steve
