Product Description:
Hawks Motorsports is pleased to offer our clients the following 2016-2019 Cadillac CTS-V LT4 6.2L 1-7/8" x 3" Stainless Steel Long Tube Headers by Kooks, part number 23122400. These long tube headers are designed specifically for the supercharged 6.2L LT4-powered Cadillac CTS-V and feature 1-7/8-inch mandrel-bent primary tubes flowing into 3-inch collectors.
The LT4 already has plenty of blower noise and horsepower to back up its attitude, but opening up the exhaust side is where a serious CTS-V build starts sounding like it means business. These 1-7/8-inch Kooks long tubes give that supercharged 6.2L a larger path out of the cylinder heads while feeding into 3-inch collectors, making them a solid foundation for a hard-charging street or performance-oriented exhaust combination.
Kooks builds these headers from 304 stainless steel with 3/8-inch thick laser-cut flanges, oval ports, and a stock bolt pattern. The headers use 1-7/8-inch mandrel-bent primary tubes and 3-inch collector outlets with Torca Swivel-Seal-style connections.
These headers do not connect directly to the OEM exhaust. A compatible Kooks connection pipe system or Kooks header-back exhaust system is required to complete the exhaust configuration.
