FLOWTECH equal length long tube headers are designed for 5.0L Mustang and Capri owners who demand maximum power and performance. These true equal length headers are built from select lengths of mandrel-bent 1 5/8" tubing, including FLOWTECH's exclusive Power Plenum collector. This header is also equipped with an oxygen sensor fitting that accepts the stock sensors.(Available in your choice of finishes.)
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.
