The first scan shows a muffler. I do not have that, just the high loop that it shows.
The second pic says"Deisel"(Correct spelling is diesel
) but it's pretty much the same as mine except for the fact that mine is NOT galvinized pipe. It has no, none, zero, zippo, corosion from 46 years in a boat. I'm thinking mine is actually Stainless steel.

Third is a photo of my exhaust.
