Are you saying that your converter is getting hot enough to glow orange? If so, this is a new one to me.

I've been in Dyno booths and have seen entire exhaust systems glowing orange. But that's with the motors running at sustained r.P.M.S of 5,000+.

If yours is glowing like that all the time, I'd say raw fuel is pouring into your exhaust. But if that's the case, Your engine should run like crap, all the time. And you'd get constant backfires as well.

You should take your car to an exhaust specialist.
