    Patriot offers affordable racing headers for many applications in the popular IMCA Modified, Sprint Car, Late Model Sportsman, Street Stock, Mini-Stock and Pony Car classes. Patriot headers use precision machined flanges and lightweight but strong 18 gauge tubing. Mandrel bent primaries and long transition collectors reduce backpressure for increased exhaust velocity. Some applications are available with a stepped pipe design to help broaden the torque curve for better corner acceleration. Available with our optional metallic ceramic thermal barrier coating which is corrosion and heat resistant up to 1600ยบ F providing increased thermal fatigue protection and lower under hood temperatures.
