Here are the pictures of the mufflers. Maybe somebody here can tell us what brand they are. As I mentioned before, I don't know because they were there when I bought the boat.

In the second pic, you can see the outline of a logo on the top which looks very much like my HPI mufflers(now aquapowerltd.com).

Here is a pic of my Gibson mufflers. They look very similar so may be them.

They look like HPI's, but the internal flapper is throwing me off

Yep, but my internal flappers are part of my Merc Racing tips from header to transom. That may be what you are seeing.

Good news! We finally got around to finishing the swap and the new Stellings are installed. Here are a few pictures taken with a camera phone. I left the mufflers on rather than installing regular exhaust tips, but I am wondering if I can remove the internal flapper since we have the rubber ones on the outside. You can hear the internal ones "flap" open and closed at idle. No bid deal, but if I could get rid of that noise I would. Any ideas?
