Thermal Coating Info-
This reflective heat barrier coating is a zirconium ceramic based blend that offers an effective method for controlling thermal engine issues.  It is applied internally and externally for ideal effectiveness.  Maximum effective temperature is 2,200 F.  The use of this coating on the exhaust manifolds has benefits of negating the need for a heat shield, protecting the stainless from fatigue (strengthening the manifold),  and also maintains high exhaust gas temperatures, creating faster travel and better scavenging.  It is highly recommended on these manifolds!
