Ford Econoline, E-350 V8, 7.5 lt multiple exhaust Published by manual-mecanica

The exhaust manifolds turn red after driving for a short time. It's a catalytic converter V8, 7.5L. The converter was removed, the timing was adjusted, but they're still red. The engine runs at normal operating temperature. I don't know what the problem is. Can anyone help me?

If they are heavily carbonized by soot or oil residue, it is common for this to happen; the other possibility is that it does not evacuate the gases well due to valves that are too closed or obstructions in the line, at least that's what I've seen in similar cases.

I already check it and do not have what you indicate, but on the other hand the compressor injects air into the multiple and the converter, I do not know if that is the cause of the multiple temperature rising, do you know anything?
