When it comes to horsepower and torque, outflow is just as important as inflow. K20 exhaust headers from AutoZone fine-tune your gas pulse by lowering the pressure of exiting fumes. Factory manifolds tend to wear down much more quickly, but our aftermarket exhaust header for Chevy K20 features a high-strength build and weather-resistant coating. Performance manifolds also give you a lot more power and even extend the life of your engine.
