Kooks 2" x 3" stainless long tube headers — the step up for built CTS-V LT4s (heavy pulley swaps, headwork, stroker builds) where the 1-7/8" tube becomes the bottleneck. The 2" primary keeps the upper RPM range open on built supercharged LT4s. 304 stainless construction with 3/8" thick laser-cut flanges and Torca swivel-seal connection.
Fits 2016-2019 Cadillac CTS-V (LT4 6.2L supercharged). Requires Kooks Gen 3 CTS-V connection pipes downstream.
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 supercharged heat and corrosion.
Pair with Kooks Gen 3 CTS-V connection pipes (PN 23123100). Replacement Gen V LT gaskets (SS-755897) sold separately.
