Engineers, Metallurgists, and other experts out there will state that there is no way that the material can fail because it can withstand, and it was designed to withstand, the internal temperatures of exhaust gases. TRUE! But, when the header is not allowed to cool so as to dissipate those extreme temperatures that the wrap is controlling, you have now developed a heat absorption that compares to thermal friction which will will continue to gain in temperature beyond the normal exhaust gas temperatures (EGT's). This is the same as with most any insulation.
The EGTs stay the same but the properties of the header material changes in a way of amplifying the temperatures because of the insulation. This action goes against normal laws of thermal dynamics, but this effect is fact, and you have to pull the ears off most engineers before they believe you. This is the trouble with plenty of education, but NO "common sense"!
Insulation will cause a header material to reach temperatures higher than the exhaust gas it�s exposed to? Maybe if its sees significant frictional heating from the exhaust flow, but how big an effect is that?
"properties of the header material changes in a way of amplifying the temperatures because of the insulation"
Amplifying the temperature? WTF?
To use his terms:
This is the trouble with no education, an ignorant man stringing together technical sounding terms without any real understanding of thermodynamics. Throw in a little crude humor; make fun of the professionals and half the fools out there will buy it.
