Sprint Car Header 1- 3/4in x 1-7/8in LS1

The Sprint Car Header 1-3/4in x 1-7/8in LS1 is a precision-engineered exhaust manifold designed specifically for high-performance sprint car racing and dedicated track applications. Manufactured by Schoenfeld, a well-known name in motorsports exhaust systems, this header is essential for racers looking to enhance their vehicle's performance. It is particularly suited for LS1-based powerplants, providing a competitive edge in various racing classes.

This header features dual-diameter primary tube construction, with 1-3/4-inch tubes transitioning to 1-7/8-inch collector sections. This design optimizes scavenging efficiency and maximizes horsepower extraction while balancing low-end torque and high-RPM flow dynamics. Constructed from mandrel-bent, high-temperature steel tubing, it is built to withstand extreme exhaust temperatures and vibration loads, ensuring durability and reliability in competitive environments.

Sprint car teams utilizing LS1 engine packages, whether in IMCA Modified, USAC sprint, or local dirt-track classes, will find significant performance benefits from this header. Its stepped primary design reduces backpressure and prevents reversion, allowing exhaust gases to exit efficiently across the entire rev range. This header is a vital component for those seeking to unlock untapped performance while maintaining structural integrity under racing conditions.
