No, not from the photo, but from the fact that you obviously don't know what you're looking at.
I'm not trying to be harsh, but if you can't identify a muffler by sight, you do not have the knowledge you need to make an assessment of your exhaust system!
OK, here's some tips that may help you:
First, shoot the whole system with an IR thermometer, look for hotspots, and feel for soft spots that could mean delamination.
Check for leaks, or white powdery stuff where it has leaked
Check all the clamps for rust and proper fit.
Supports and hangers in good shape, not pinching or bending hoses
No low spots that would hold water.
Make sure the entire run slopes down towards to the transom.
Is the transom outlet above the waterline?
There is lots more, but without getting too technical, thats some basic stuff that you can do to verify that your system is OK.
