  • High flow, mandrel-bent tubes provide consistent tubing diameters for smooth flow and increased exhaust velocity
  • Heavy duty tubing and high quality welds for increased strength and durability
  • Smooth transition, 1-3/4 diameter primary tubes are used for increased exhaust flow increasing performance, improving throttle response and broadening the torque curve
  • 3 slip-on collectors connect to a 3 high flow Y-pipe that connects at the factory exhaust location
  • TIG-welded, machined 3/8 header flange for a leak-free seal and maximum strength
  • Premium aluminum header gaskets and installation hardware included
  • Available in a high heat resistant black paint or a satin silver metallic ceramic thermal barrier coating
  • Connections for O2 sensors are located on collectors. Catalytic converter must be relocated
  • Headers are a must if you are using a cold air intake, cat-back exhaust system or tuner
