Reposting here since I didn't get any answers in General Q & A, does anyone know what these cans are that are welded to my tails on 1990 357 SR1 420/TRS? First time I have seen them so I am curious.

Mufflers or baffles maybe. Any lines going to them?

Negative on the lines, I don’t feel like pulling it apart to see so I was hoping someone would know.

My guess would be some type of muffler, since the flapper is usually in the tail piece. What else would you do to an exhaust?

I vote for muffler, or a flux capacitor

I always install the flux capacitor on the shifter. easy to get to.

That's what I am leaning too as well, just "baffles" me as to why you would need additional mufflers with the silent thunder platform.

I like my flux capacitors spinning outward.

On a side note, I opened up the silent thunder platform as I have all previous birds and this boat much quieter than ones in the past. I am going to have a closer look when I put the tails to put in new gaskets and plates - might end up cutting the off to let her exhale a little better.

Let the bird breathe!!!! I was so happy once i finally pulled the box off. I like the looks of it but at the same time I love the new aluminum platform.
