WARRANTY NOTES
1) The utmost care is taken at Thorley Headers to maintain the highest standards of quality.
However, Thorley Headers cannot control the installation of the product. For this reason, the
Thorley Headers warranty covers only the replacement of the components - not the labor for
the installation.
2) The use of any type of "header wrapping" voids the warranty. Using any sort of wrapping
material on the headers destroys the tubing's ability to dissipate heat, causing very rapid
deterioration of the metal and the subsequent failure of the headers.
3) The chrome plating applied to all Thorley headers is a high-nickel chrome finish applied to
retard corrosion. This is a "heat" chrome to preserve the metal. This finish is not "show
chrome" intended for the sake of appearance. This high-nickel chrome turns colors and
approaches black as it cooks into the metal. The brilliance of the chrome finish is not cov-
ered under the warranty. Contamination of the surface by foreign substances may produce
other color patterns. This can be prevented by routine cleaning.
