Header Sprint Car/Dyno 1-3/4 LS1

The Header Sprint Car/Dyno 1-3/4 LS1 by Schoenfeld is designed for serious LS1 engine builders and dyno enthusiasts who seek to maximize exhaust scavenging and power output. This header is ideal for dedicated sprint cars, drag strip competitors, or vehicles used for test-and-tune sessions, showcasing Schoenfeld's extensive racing heritage in tubular exhaust manifold engineering.

Featuring a 1-3/4-inch primary tube diameter, the header is engineered to optimize exhaust gas velocity throughout the entire RPM range of LS1 engines. Constructed from heavy-gauge mandrel-bent steel tubing, it employs an equal-length tube design that promotes balanced cylinder flow and minimizes exhaust reversion, enhancing overall efficiency. This design prevents excessive backpressure while maintaining sufficient velocity for forced-induction applications.

This header is perfect for LS1 crate engine swaps and bolt-on modifications on naturally aspirated platforms, making it an excellent choice for baseline dyno testing. It pairs seamlessly with aftermarket intake manifolds and fuel injection systems, ensuring compatibility with a wide range of performance setups.
