Mystery Piece of Stainless in my Exhaust Tip - please help identify
 

I found this mystery piece of stainless trapped in my port tailpipe. It is oval shaped and approximately 3.25" X 2.5". Heavily corroded too. It's not out of the tailpipe - way too small. I don't think it would be out of the CMI headers. My best guess it was part of the stainless intermediate y-pipe (non-switchable) that allows the exhaust to go out either straight out or through the bravo transom assembly below the waterline. The vertical part of the y-pipe does have this same oval shape. Anyone ever seen this? Should I be concerned? Thanks.

I think it could be part of the wire mesh inside the rubber exhaust hose. has it ever lost an impeller and gotten hot?

my guess too!

Look inside the tail. There's a short, inner, tube where the water enters that works like a baffle to keep the water going in the right direction.
