Check to see if the engine is overheating, then check the exhaust system to see if it is clogged. If it is clogged, find out the reason why before just replacing exhaust components.

I have seen this problem 3 times, once it was because the distributor was in wrong and the ignition timing was way off, the second time i saw the problem i found a bad Throttle Position Sensor. The third time i found that the timing chain had jumped a few teeth and thrown off the valve timing. A clogged exhaust system will not cause this problem as i have seen numerous (completely)clogged Catalytic Converters and the chief symptoms are: lack of power or no start.
An overheating motor will not cause this problem either. I've lost count of how many overheated motors I've seen and that has never caused a glowing exhaust.
I would begin by using a timing light and check ths base timing, then scan the motor to see if you have a bad Throttle Position Sensor.

If it's glowing red you have a vaccum leak someplace, probably in the intake manifold or the engine is running lean on fuel or possibly too rich as the unburnt fuel is burning in the exhaust.

No but an engine running like that can damage the valves.
What would make a 93 talon tsi turbo exhaust manifold to glow red HOT but the car is not over heating and it still runs good and it has a new cadillac converter please any help?
check the cad. converter ======================== That's normal if you dive the car "HARD" .. Turbo kicks in and lots of air/fuel => exhaust then too hot
Why does back turbo get cherry red just after a few minutes of driving?
The back of the turbo, is the turbine. It has the hot exhaust gases flowing thru it. The exhaust gases are 1000+ degrees f. and cause the steel to glow red/yellow when under load.
Why does the exhaust manifolds on your 2000 E250 4.2 get red hot?
Normally a blocked catalytic converter or a blocked exhaust will cause that problem. Back pressure, means the gasses cannot escape. thus causing the manifolds to glow.
