Headers are specifically designed to provide significant increases in horsepower and torque throughout the entire RPM range. Metallic Ceramic Thermal Barrier Coating (MCTBC) is applied to headers for added durability, reduced underhood temperatures, and increased performance. Available Tri-Y headers use uniquely paired primary tubes with a four-into-two-into-one design that increases mid-range power without sacrifices in top end. All headers are sold complete with necessary gaskets and fasteners.
