Beach Debris: What Is This?

Spotted this very rusty item on Driftwood Beach this morning. It was about 2 feet long. Any ideas on what this is?

I asked my husband ( he’s an engineer) and he said : in this state, it could be anything : that’s no help 😂
So what do you think it is ? It looks heavy ...

Looks like part of an exhaust to me the silencer. Been in the elements a long time!

@koalagardens @momamo @janbell Like Jan I thought it might be a muffler/exhaust system. I also agree with KG that it looks to have been in the ocean for a long, long time! Thanks for your comments.
