-Package included:
1 * Exhaust Header Kit
-Feature:
1.Maximizing air intake and exhaust outflow is crucial for enhancing engine performance, making exhaust headers a vital component as the primary outlet of an exhaust system. These performance headers optimize airflow by replacing the restrictive exhaust manifold that comes standard with your vehicle.
2.By providing each cylinder with its own individual exhaust pipe, headers prevent interference between cylinders and eliminate the back pressure commonly found in stock exhaust manifolds.This allows cylinders to expel their exhaust without obstruction, resulting in increased power transmission to the wheels. When combined with a high-performance cold air intake and cat-back exhaust system, a header system eliminates all engine restrictions, enabling it to operate at peak efficiency.
