Race car headers replace factory exhaust manifolds to improve exhaust flow and increase engine performance. Performance headers are designed with optimized tubing lengths and smoother bends to reduce exhaust restriction and improve engine efficiency. These upgrades are commonly used in motorsport and high-performance builds to increase horsepower, enhance throttle response, and improve overall engine performance. Motorsport Locker provides a marketplace where racers and builders can buy and sell new and used race car headers designed for race engines and high-performance vehicles.
