Product Details

Kooks Headers Long Tube Exhaust headers are performance long tube exhaust headers built to replace restrictive factory exhaust manifolds. They improve exhaust flow and scavenging, which helps the engine make more horsepower and torque. Many applications also pair the headers with catted Y-pipes or catted connection pipes, so you can get a complete header and connection package.

Key Features:

  • Long tube design that improves exhaust flow and cylinder scavenging over stock manifolds
  • Stainless steel construction for durability and corrosion resistance
  • Primary tubes sized for each application to balance power and drivability
  • Options with high-flow catalytic converters (catted connections) for lower emissions
  • Precision-fit flanges and CNC-formed tubing for consistent, accurate installation
  • Available as headers only or as header and connection kits, depending on the part number

Kooks Headers is known for its American-made exhaust components, and each line is engineered for strong performance and a good fit. Check the individual part number for the specific configuration, connection type, and what is included.
