What does a header do? It allows your engine to expel hot gases efficiently. The flow from the engine comes through the headers, to the catalytic converter and out your exhaust. The better we make the process of moving the gases out, the better your Honda Fit performs. A header can easily bump up the power and torque the car produces.
