Sato baffle transplant
I was going along with Nemo's guide on repacking Sato pipes, and ran into the same problem as him, the baffles are shot on one end.
I'm not really mechanically sound, so I was running this idea through my head. If you take some baffles from an otherwise quiet pipe and transplant them into the Satos (as long as the diameter matches) will the Satos run quiet, or will they still be loud? Not really sure how much a baffle affects the loudness of a pipe.
