Getting more air into your engine and more exhaust out is the key to a performance motor. That's where exhaust headers come in. Exhaust performance headers do away with the performance-robbing exhaust manifold that came with your car. Headers provide each cylinder with its own mini exhaust pipe, which means exhaust headers prevent the backpressure that occurs in a common exhaust manifold. When cylinders don't have to fight each other to expel their exhaust, they can put more power through the wheels. Combined with a high performance cold air intake, and a cat-back exhaust system, a header system will remove all restrictions and your engine will perform at its potential.
