FLOWTECH headers are precision engineered and leak tested to get maximum performance and fuel economy from your engine. Each header is formed from specially selected .049 cold roll flash controlled tubing, and features FLOWTECHs exclusive, thick, mandrel-formed Power Plenum collector. All ports are precisely fitted and finished with sturdy, leak-proof O-ringed port seals, and all FLOWTECH headers include all mounting hardware including bolts, nuts and premium gaskets. FLOWTECH headers are available with either a high-quality satin black paint finish or with a specially formulated, NASA-developed silver luster ceramic coating for rust and corrosion resistance.

| Description_ASC |
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. |
