It is tough to measure maximum temperature of an exhaust manifold. The peak temperature occurs during full power extended operation such as racing or pulling a trailer up a hill. I have seen engines running on a dyno and the exhaust headers glow bright red under power. When you take a measurement at home with the engine idling and the hood open that is not even close to maximum temperature. Exhaust paint should be rated for over 1000 degrees.
