Product Description:
Hawks Motorsports is pleased to offer our clients the following 2016-2019 Cadillac CTS-V LT4 6.2L 2" x 3" Stainless Steel Long Tube Headers by Kooks, part number 23122600. These long tube headers are designed specifically for the supercharged 6.2L LT4-powered third-generation Cadillac CTS-V and feature 2-inch mandrel-bent primary tubes flowing into 3-inch collectors.
For the CTS-V owner building an LT4 that needs more room to breathe, a set of 2-inch primary long tubes is serious business. These aren't just a cosmetic underhood upgrade—the larger primaries and 3-inch collectors are built for a combination where the supercharged LT4 is moving a lot of air and the exhaust system needs to keep up. Whether the car is staying close to stock or headed toward a more aggressive build, these Kooks headers provide the foundation for a full performance exhaust setup.
Kooks constructs these headers from 304 stainless steel and uses 3/8-inch thick laser-cut flanges, oval ports, and a stock bolt pattern. The 2-inch mandrel-bent primary tubes feed into 3-inch collector outlets with Torca Swivel-Seal-style connections.
These headers do not connect directly to the OEM exhaust. A compatible Kooks OEM connection pipe system or Kooks header-back exhaust system is required to complete the exhaust configuration.
