Schoenfeld SBC Chassis Headers 1-3/4 - 1-7/8 152EV

Optimizing exhaust scavenging is critical for small block Chevy power plants in circle track competition, and Schoenfeld's chassis headers deliver measurable gains in mid-range torque and top-end horsepower. The stepped primary tube design (1-3/4" to 1-7/8") balances velocity across engine speeds while the 3-1/2" collector efficiently consolidates exhaust gases, reducing backpressure and improving engine breathing. Built from quality steel and finished in durable black paint, these headers are engineered to withstand the thermal and mechanical demands of sustained racing without compromise.
