Description
Extracting maximum horsepower from your Small Block Chevy requires a header designed specifically for competition demands—and Schoenfeld’s IMCA Modified configuration delivers proven gains in exhaust scavenging and throttle response. The stepped primary tubes (1-3/4″ to 1-7/8″) optimize low-end torque while the 3-1/2″ collector efficiently consolidates exhaust flow, translating directly to measurable ET improvements on the circle track. As a complete bolt-on kit with black-painted steel construction, this header gives you race-proven engineering without custom fabrication delays.
