Warranties

AHC coated headers will burn and be damaged at exhaust temperatures above 1300 degrees. An excessively lean fuel mixture can generate exhaust temperatures over 1700-1900 degrees. If the coating is burned (which will look like a dull gray) due to a lean condition, it is not warrantied, but the headers can be recoated.

Not legal for sale or use in California on pollution controlled motor vehicles.
