Key Features
- Getting more air into the engine and allowing exhaust gases to exit more efficiently are important factors in engine performance. Exhaust headers play an important role in the exhaust system by improving exhaust flow compared with the more restrictive factory exhaust manifold.
- Headers provide each cylinder with its own individual exhaust tube, helping reduce interference between cylinders and the back pressure commonly found in standard exhaust manifolds. When the cylinders can expel exhaust gases more efficiently, more engine power can be transferred to the wheels. When combined with a high-performance cold air intake and a cat-back exhaust system, a header system can help reduce airflow restrictions and allow the engine to perform closer to its full potential.
