The exhaust gas gets up to around 500-600 C, but exterior to the pipe nowhere near that hot. I put a K-type thermistor inside the cat shell, for my curiosity, on my Corolla which has the cat located under the floor. My highest reading was 260 C, IIRC. Inside the engine bay with grille blocks it could be hotter, but I'd bet against anything much over 350 C, even touching the exhaust manifold.

I remember someone around here having a fire blanket attached to the hood. I can't find the thread or remember who it was.

EDIT: I remember now:
