Long Tube Header for 1970-1973 Ford Mustang 351C-4V Black Paint 12118FLT Flowtech

Overview:

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.

Fitment Notes:

• Will NOT fit with manual transmissions.
• Will NOT fit C6 transmissions (but fits other Automatic Transmissions).
• 351C-4V engines only!
• WILL fit models with AC, Power Brakes, and Power Steering.
• 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.
