Mititempo and JimsCal, thank you. but i spent some time talking to silicone hose distributors. I haven't gotten to the actual manufacturer, but the distribution network challenges your conclusion: meltdown. They say, some of it, anyway, will withstand 500 degrees F. that's enough headroom to do what I need (I think).
Engineering question: if i measure the surface temp of the existing metal exhaust at the hottest point, just after the water-injected riser, and the black-iron reads, say, 300, how hot is the gas inside?
