Kooks GM LSX DR header flange — for the GM LSX DR raised-port head used in serious LS / LSX race builds. The DR head's D-shaped port differs from standard LS port geometry and requires this application-specific flange. For fabricators building dedicated race headers.
Fits the standard DR head bolt pattern. D-shaped port matches the DR head's port geometry for unrestricted flow with 2-1/8" 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 2-1/8" J-bends and merge collectors for a custom LSX DR header.
