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. FlowTech
recommends using cast iron exhaust manifolds
or old Headers
to break in new engines to avoid coating damage. Please call FlowTech
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. FlowTech
does not recommend the use of header wraps as this will void the warranty.
