A week or so ago I asked about muffeling the exhaust on my boat.

One person (Dave) suggested:

You might be able to simply slide a baffle into the exhaust outlet.
They are good for taking the rasp out of the exhaust note and they are
simple to install (and remove if desired).

I've looked around a bit but haven't found any such devices. (Not in-line
mufflers, but baffles that can just be "inserted" into the exhaust outlet.

Anyone know where to find information on these?

I bought a set of them 9 years ago to take the edge off of the "bark"
of my exhaust note. I forget where I got them from, but it was a
company who advertized in the back of one of my boating magazines.

Basically it's a slide in "basket" with slots which attaches to the
protruding lip of the exhaust pipe with a single bolt and nut (if your
exhaust outlet is flush to the transom, you might have a problem).
They make them for 3" and 4" diameter pipes. I had to grind a slight
amount off of mine to allow them to slide in smoothly.

I'll look at my magazines and see if I can find the company again.
