TIP: Breaking in an engine with ceramic coated headers WILL result in
damage to the coating and will void all warranties. Ceramic coated headers
require several heat cycles to fully cure before they will withstand
extreme heat. Hooker recommends using cast iron exhaust manifolds or
old headers to break in new engines to avoid coating damage.
