Key Features
Requires Flowtech air conditioning bracket 10042FLT. May require clutch linkage modification. Does not fit with angle plug heads. Breaking in an engine with ceramic coated headers WILL result in damage to the coating and will VOID all warranties. C
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 and corrosion resistant metallic ceramic thermal coating that increases exhaust velocity and reduces underhood temps for increased performance.
