[More Info]
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.
Features:
  • 3/8" Thick machined flanges to prevent warping
  • CNC mandrel bent tubes for ensuring accurate fit and optimal flow
  • Heavy duty 16-gauge tubing for long life
  • Tubes are pre-polished to removed scratches before applying metallic ceramic or hi-temp black coating
