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 mini exhaust pipe, which means exhaust headers prevent interference among cylinders; thus, the back pressure that occurs in common exhaust manifolds. When cylinders don't have to fight with each other to expel their exhaust, they can put more power through the wheels, pushing the vehicle. Combining with a high performance cold air intake, and a cat-back exhaust system, a header system removes all restrictions of your engine, then, it is able to perform at its full potential.
