Re: Exhaust manifold questions...
I have not kept up with the previous Jet Hot discussion, is
this a coating on the outside of the manifold/exhaust pipe
or is it on the inside? If it is on the outside, then how
does it actually reduce the thermal stresses on the exhaust
manifold? It would seem that they would increase from the
heat being retained inside the manifold. I need a little
help understanding this....
