Not sure if this is "anecdotal" evidence, but JetHot-ing sure looks cool !

As long as we're on the (neverending) topic of heat management--thermostats,
etc.--has anyone done a before/after analysis of manifold/downpipe ceramic
coatings (JetHoat, etc.) and the effect on engine temps? I know we've
discussed it before--and there seems to be some anecdotal, positive
results--but does anybody have any definitive info to add?
I wrapped my downpipes, and the net result was seemingly hotter gases at the
exhaust exits--I didn't actually measure the temps, but the exhaust went from
hot to pistol hot--circumstantial evidence that more heat is being moved away
from the engine compartment. I can't say I saw a measurable decrease in
coolant temp, but unless you do before/after testing under identical ambient
conditions it's going to be subjective at best.
