Nothing ventured nothing gained. As a one-off in a specific lower-than-tyical heat application it may last for a little while. That design is pretty much how my mufflers look and they weigh 12 pounds in 321 stainless. I would love to use aluminum as it is less expensive and lighter but it is nowhere near as durable as 321. You have seen those pictures of cherry red glowing turbos yes? That would turn your muffler into a vulcano.
Is your muffler packed or a perforated chamber?
