Flowtech 49100FLT – Afterburner Headers
Flowtech Afterburner Headers represent the first new major design change in exhaust technology in decades. They have a patented velocity tube design, which will increase scavenging and smooth exhaust pulses. These afterburners are available with a primary collector formed from steel, and a large 3 in. secondary collector. 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. 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.
