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.This fitment is tailored for popular aftermarket engine swap kits. Doug’s engine swap headers were developed to solve common fitment issues in tight spaces, making your swap process smoother. No more guesswork or modifications needed – just straightforward installations that save you time and frustration.

• 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
