Sprint Car Headers 1-5/8 - 1-3/4

The Sprint Car Headers 1-5/8 - 1-3/4 from SCHOENFELD represent a purpose-built exhaust solution engineered for high-RPM sprint car competition and extreme engine applications. These headers are designed for drivers and teams seeking maximum scavenging efficiency and unrestricted exhaust flow in short-track racing environments. If you're building a sprint car engine or upgrading an existing platform for improved power delivery and throttle response, these headers deliver the thermal management and performance characteristics demanded by competitive motorsports.

SCHOENFELD headers utilize stepped tube diameters—1-5/8 inch primary tubes transitioning to 1-3/4 inch collector sections—to optimize exhaust gas velocity across the RPM band while minimizing backpressure. This stepped design improves cylinder scavenging by creating ideal wave dynamics that pull spent gases from the combustion chamber more efficiently than traditional single-diameter designs. The larger collector diameter reduces flow restriction at peak power, critical for sprint car engines operating at 7,000-plus RPM. Constructed from mandrel-bent tubing and finished for durability in harsh race environments, these headers weigh 34.8 pounds and measure 20.6 x 10 x 37.75 inches—compact enough for tight engine bay layouts while maintaining proper tube separation and heat management.

Sprint car competitors, short-track racers, and engine builders benefit most from SCHOENFELD headers when pursuing horsepower gains and consistency on the dyno. Installation requires proper exhaust manifold-to-header sealing and compatible collector piping; verify clearance in your specific chassis and engine bay layout before purchasing. These headers pair effectively with modern fuel injection systems and standalone ECUs, allowing tuners to optimize air-fuel ratios for the improved scavenging characteristics. For serious sprint car programs or high-performance builds demanding proven exhaust technology, these headers deliver measurable power gains and reliability.
