These uncoated headers are manufactured in the USA by Hedman Hedders and are backed by a limited lifetime warranty against defects including cracks in tubes and welds. The temporary black paint provides protection during shipping and storage but will burn off during normal operation. For long-term protection, high-temperature coating is recommended.
