How good exhaust headers benefit your cars? 

Getting more air into your engine and more exhaust out is crucial for a performance motor. This is where exhaust headers come into play as the first step of an exhaust system. Performance headers optimize air flow, replacing the restrictive exhaust manifold that came with your vehicle.

Headers provide each cylinder with its own mini exhaust pipe, preventing interference and reducing back pressure that occurs with common exhaust manifolds. When cylinders are not competing to expel exhaust, they can deliver more power to the wheels, enhancing vehicle performance. Combined with a high-performance cold air intake and a cat-back exhaust system, headers eliminate all engine restrictions, allowing it to perform at its full potential.
