    Note: This product is Legal for use on 1974 and older non catalyst equipped vehicles and isconsidered a "replacement part" per California Air Resources Board regulations, as long asALL emissions sensitive components are retained, including A.I.R., EGR, Heat Risers etc.Failure to retain any of these components, or use on any 1975 or newer catalytic converterequipped car would render this product Illegal for Street or Off Highway Use in California, orin states that have adopted California Emissions regulations and may only be used for ClosedCourse Competition.
    • 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.

      Chassis headers fit inside the frame rails, but if there is not enough room, our "up and over" fenderwell headers will provide the same great performance with an awesome look.
