Breaking in an engine with ceramic coated headers WILL result in damage to the coating and will VOID all warranties. Flowtech recommends using cast iron exhaust manifolds or old headers during your engine break-in period to avoid damaging your coated headers. Please call Holley tech service at 270-781-9741 for additional information regarding ceramic coated exhaust products. The use of header wraps can cause the header tubes to crack or rust due to excessive heat and moisture build-up. Hooker does not recommend the use of header wraps as this will void the warranty.
