3000°C! That's higher than the glass point of glass or the melting point of steel. That seems unsustainably hot. It makes me think I should be careful about adding insulation to my cat. Fiberglass batt would be too much; I'll just wrap it in a few layers of aluminium foil to replace the rattling heat shield.
Opps, left axis on the catalytic converter temperatures. Closer to 600-700 C.

I'll post the data later. In the meanwhile, here is Google link of the test route I used.
