Kooks LSX header flange — for GM Performance's strengthened LS-platform iron block used in high-output and racing applications. The LSX block uses a different head bolt pattern than the standard LS, so this LSX-specific flange is required for LSX custom builds.
Fits the LSX-specific bolt pattern. Round ports sized for 1-3/4" primaries.
Kooks Headers & Exhaust has been hand-building stainless headers and exhaust systems in Statesville, North Carolina since 1962. Every component is fabricated by experienced fabricators in the same shop where the company's racing roots were established. 3/8" thick 304 stainless steel resists warping under race-level heat cycling.
Sold individually. Pair with Kooks J-bends (1-3/4" diameter) and merge collectors for custom LSX header fabrication.
