All CMI headers are designed to outperform most conventionally cast manifolds because CMI headers are lighter and freer breathing. Long tube-style headers, like CMI Sport Tubes and CMI Big Tube headers, enable naturally aspirated engines to reach peak performance power through more efficient exhaust scavenging and improved exhaust tuning.

For blown and supercharged engine applications, short tube-style headers, like CMI Elbow-Top, CMI Elbow-Top Light, CMI Unitop, and CMI Big Elbow-Top headers, perform similarly to, and in some cases better than, long tube-style headers. Short tube-style headers are also typically less expensive.

For applications where CMI Big Tube and Big Elbow-Top headers are required, CMI offers a range of primary tube diameter sizes to optimize engine torque and boost horsepower.
