Turn down Muffler ?
 

Whats everyones thoughts on these? How quiet is it at Idle/no wake?

I like the idea of my boat being quiet around the docks/slips/buoy patches.

Also, and most importantly, are flappers necessary with these?

Thanks

They work very well. What type of boat and engines? We have had numerous made for different boats.

Very quiet. Similar to through prop exhaust, although not quite as quiet.

OK, how about the flappers? My current tips have the externals, the internals burnt out long ago.

Thanks,

You should replace the internal flappers.

I'm guessing you are talking about what is refered to as "donkey d!cks", if so, check this thread about them.
