Kooks 1-3/4" x 3" stainless long tube headers built specifically for the redesigned GMT K2XX platform's updated exhaust packaging. The 2014+ trucks have different chassis routing than the prior generation, so these long tubes are application-specific. 304 stainless construction with 3/8" thick laser-cut flanges and mandrel-bent primaries.
Fits 2014+ GM 1500 Series trucks and 2015+ SUVs (5.3L / 6.2L) — Silverado, Sierra, Tahoe, Yukon, Escalade. Oval port, stock bolt pattern.
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 salt-belt corrosion.
Pair with the appropriate Kooks Y-pipe (PN 28603100 for 5.3L; PN 28613100 for 6.2L). Replacement LS gaskets (SS-755818) sold separately.
