Get to a mechanic quickly. You could end up with a car fire from it over heating.

raw fuel down the pipes, late timing will do it

Or a leaking fuel injector.

Cat is probably clogged and cant process the exhaust properly anymore. I've seen it before where they actually glow red from the heat they produce when the catalytic converter fails.
