You are bidding on a Brand New Pair of Flowtech Long Tube Headers, Painted Black Finish, 3" Collectors with Oxygen Sensor Fitting, 1.625" Primary Tubes, Compatible with 1979-1993 Ford Mustang & 1979-1986 Capri (Part #12104FLT)

Flowtech headers are the perfect combination of performance and value. Flowtech long tube headers are precision engineered using mandrel bent tubing, formed collectors and 5/16" flanges with sealing rings for a leak-free seal. All mounting hardware and gaskets are included for a simple installation. This header is coated in a high heat resistant black paint for a stealthy appearance.

NOTE: Breaking in an engine with ceramic-coated headers WILL result in damage to the coating & will VOID all warranties. These headers require several heat cycles to fully cure before they will withstand extreme heat. Flowtech recommends using a cast-iron exhaust manifold or an old header to break in new engines to avoid coating damage.
