TTI FOOTNOTE # C4

CERAMIC COATING is a silver matte finish applied to the steel surface to protect against rust and corrosion, extending part life.  Withstands temperatures up to 1200°F, reduces under-hood temperatures by 50 degrees and will not discolor or blue.

The THERMAL BARRIER is a protective inside coating which increases part longevity, by protecting component parts from thermal fatigue.  (2-year Limited Warranty)

Warning:  First Engine Runs

TTI strongly suggests that you use an old set of headers or set of cast iron manifolds for your first engine run / cam break-in.  This will insure that you will not damage the coating and void the warranty of your new headers.  Header coating damage usually occurs during the first engine run / break-in when the exhaust temperatures exceed 1200ºF.  Excess exhaust temperatures are normally caused by excessively rich or lean air / fuel mixtures and / or incorrect ignition timing.
