New purchaser Pleasure Way Plateau TS 2006

Okay, Bob says, in corrobation with Asheguy, that it's essentially a muffler. But it's a pressure-relieving muffler hence the decapacitation when it gets a leak. Per Bob leaks commonly occur, like ours, when the seam "between the round half and the flat half" fails.

I'm wondering if the "resonator eliminator" is the metal version I mentioned.
