Glowing manifold/turbos
Is glowing manifold a problem? The car idled for about 20min, may be half an hour max and the manifold/turbo housing started glowing. I can't see it when it's light outside but I just noticed it today as it was getting dark outside. Mods are in the sig, the only recent addition is a greddy fmic. From what I've been able to find on the forum, most people say that it's the cat or pre-cat that is clogged, but I do not have either of them at the moment. The exhaust is a straight 3" pipe all the way back to the rb single tip muffler. I've got an hks dp and it was not glowing, may be just a littlle around the flange where it attached to the exhaust hausing on the turbos.

Check workshop manual.
That was the problem at my car.

Pull into a garage and look and see if it happens on cold startup.
Probably a leaking injector, caused by a faulty o-ring. Anything that leaks raw oil or fuel into the exhaust, will cause a very high exhaust temp. This is not normal and should be addressed. You may see this intermitantly. You should not see it at all under low loads.
While it is glowing, play with the throttle. See if by revving it up that the glow subsides. If it does, there is likely raw fuel making its way into the exhaust some how....

It doesn't happen on start up, just after about 20-30min on idle. The reason I noticed it was because it was dark outside. I just adjusted my tps with the wax rod, and the fast idle, the voltages on the tps are within spec. almost exactly in the middle of allowable spec. Idle is perfect (fingers crossed) I've been battling with the damn idle for two weeks.
