Kooks 1-7/8" x 3" stainless long tube headers — opens up the GTO's cast manifold restriction with all the harnesses needed for either model year. The GTO's factory manifolds choke flow that a long tube setup immediately unlocks. 304 stainless construction handles thermal cycling and corrosion.
Fits 2004-2006 Pontiac GTO (LS1 5.7L or LS2 6.0L). Requires Kooks GTO connection pipes downstream — PN 24113100 for 2004 LS1 or PN 24123100 for 2005-2006 LS2 (the two model years use different exhaust geometry).
Kooks Headers & Exhaust has been hand-building stainless headers and exhaust systems in Statesville, North Carolina since 1962. Every Kooks header is welded by experienced fabricators in the same shop where the company's racing legacy was built. 304 stainless construction handles thermal cycling and corrosion.
Includes two (2) 12" and one (1) 18" O2 sensor extension harnesses. Pair with the correct Kooks GTO connection pipes for your model year. Replacement LS gaskets (SS-755818) sold separately.
