I had used them in the past, in two stroke racing engines expansion
chambers which, without silencer, are intolerably noisy. They worked
well. Cut the noise by more than 50% (as measured by my ear-meter).

Had to be careful not to produce too much obstruction to the exhaust
flow, though.

That was a two stroke exhaust. This is a rotary exhaust. How much
heat would it take before melting?
