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

The SCHOENFELD Sprint Car Header 1-3/4in x 1-7/8in LS1 (model 1024LVLS1) is a purpose-built exhaust manifold engineered for high-revving sprint car and dyno applications. This header set features a stepped primary tube design with 1.75-inch to 1.875-inch diameters that optimize scavenging across the RPM range, terminating in a 3.5-inch collector. Built from steel with durable black paint, the header is designed to handle sustained high-heat environments while delivering measurable flow gains over stock manifolds on GM LS-Series engines.

The stepped primary tube configuration is key to this header's performance. The transition from 1.75 inches to 1.875 inches allows smaller-diameter primaries to accelerate exhaust gases at lower RPMs while the larger transition supports peak flow at higher engine speeds—critical for sprint car engines that operate in narrow power bands. The 3.5-inch collector consolidates exhaust energy efficiently without creating backpressure. At 33 pounds per pair, this header set strikes a balance between thermal mass and weight savings. Installation is straightforward with gaskets and hardware included, eliminating the need for separate sourcing.

Sprint car competitors and dyno tuners rely on SCHOENFELD headers to unlock LS-Series potential in purpose-built race engines. The stepped primary design is particularly effective in carbureted and naturally aspirated applications where atmospheric induction dominates. Whether you're preparing for competition or maximizing engine output on the dyno, this header design has proven itself in high-performance environments. The black paint finish provides corrosion resistance for track storage and between-event transport.

LS-Series headers come in many configurations; the stepped primary design in this SCHOENFELD model is optimized specifically for naturally aspirated sprint car duty where primary tube sizing directly impacts scavenging efficiency. Forced-induction applications and street engines may require different primary diameters. This header is engineered for race applications where header selection is a tuning variable, not an afterthought.
