Key Features
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
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.
