Part Number: H8426
Skip to product information

Highlights

Full length and fenderwell headers provide the ultimate performance for street rodders with high performance engines. These header styles have longer primary tubes, which help produce more horsepower and torque than Tight Tucks.

  • Durable 18-gauge tubing
  • 1 1/2" - 1 3/4" Primary Tubing Diameter
  • 2 1/2" Collector Port Diameter
  • Oval Port Shape
  • Comes complete with gaskets, header bolts and collector reducers
  • Hi-Temp Black Coating

Why pick Patriot's Hi-Temp Black Coating?

An affordably priced alternative to our Metallic Ceramic Coating, our Hi-Temp Black finish provides good corrosion and heat protection when compared to many of the “cheaper” header finishes being applied by our competitors.
