    Afterburner Headers Break New Ground!
    FlowTech's Afterburner Headers are the latest innovation in header technology! The patented Velocity Turbo Chamber gives you more HP and torque by smoothing out exhaust pulses which in turn increases scavenging, improving your exhaust systems efficiency! Perfect for most Small Block Chevy applications, the Afterburner Headers utilize a 1.625'' primary tube with a 3'' collector giving you the torque of a Tri-Y style header with the midrange and high end HP of large tube headers! Available in either high temperature black painted or metallic silver ceramic finish. Includes all necessary gaskets, bolts, and reducers.

    Features:
  • Patented Velocity Tube increases cylinder scavenging
  • Tuned length primary tubes smooth out exhaust pulses
  • Creates more power than a comparably sized header
  • Includes gaskets, bolts and reducers for installation

    NOTE: Will not fit with angle plug heads.
