Hookers RacingHeart Big Block Chevy Down swept, 3-Step Dragster Headers feature 2.125 inch/2.25 inch/2.375 inch stepped primary tubes to maximize exhaust flow, resulting in horsepower and torque gains over a broad rpm range.

They are available in both Chrome plated Mild Steel and Polished 304 Stainless Steel.
