Key Features

  • Stainless steel construction provides the flatness retention and heat resistance needed in a high temperature exhaust application.
  • The port opening is 1 7/8 inch, designed to accept 1 7/8 inch primary header tubes for TIG welding.
  • Stainless steel, providing dimensional stability and resistance to the warping that can affect mild steel flanges under repeated thermal cycling.
  • Primary header tubes are inserted into the port openings and TIG welded to the flange using stainless steel filler compatible with the flange material.
  • This flange is machined to the same dimensional specifications used in Kooks production LT1 header manufacturing.
  • Insert 1 7/8 inch primary tubes into the port openings and tack weld to set the header geometry.
