Getting more air into your engine and more exhaust gases out is the key to a performance motor. This BuildFastCar (BFC) header helps eliminate the manifold's back pressure. So, instead of a stock manifold that all of the cylinders share, each cylinder gets its own exhaust pipe, and then they come together in a larger pipe(collector). When cylinders do not have to fight with each other to expel their exhaust, they can put more power through the wheels, which improves horsepower and torque. These BFC headers are designed to fit the vehicle assigned. If aftermarket components, parts from other applications, or custom-altered parts are used on your vehicle, it is the installer's responsibility to verify fitment.
