Interesting, John. As I said, no such issues with mine and I've now had them on the car for ~4 months... car runs/performs great... I'm just battling with an overly rich issue right now, but I'm pretty sure that's an EFI related issue (e.g: AFM gone bad... AGAIN).
Headers glow red for only one reason, there’s fuel burning inside. The two main reasons are a rich mixture and late ignition timing - which doesn’t give the fuel enough time to burn inside the combustion chamber.
Well, there IS another reason why they glow... after you've just caned the crap out of the turbo
