FLOWTECH's Afterburner Turbo Chamber Headers represent the first new major design change in exhaust technology in decades. This designs combines the race-proven 4 into 1 design with the torque managing capabilities of a Tri-Y header. The turbo chamber helps smooth out exhaust turbulence for increased performance and a broad power curve. This header is coated in a metallic ceramic coating for increased exhaust velocity and lower underhood temps.

| 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. |
