Features & Benefits

Highlights

Mid-Length Headers, often called Clippsters, are engineered to provide superior performance gains over Manifold Replacements or Block Hugger style headers. These headers enhance your vehicle’s horsepower and torque while preserving ground clearance for cars with a lowered stance and trucks where long tube headers may hang to low.

Many direct fitments with Chevy Big Blocks (396-502) are available. Please refer to the product page for applications. This product can also be used in Chevy Big Block (396-502) engine swaps.
