Description

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