Give your supercharged CTS-V the exhaust upgrade you want
Choose a matched Kooks front system for your LT4-powered CTS-V. These kits offer 1-7/8" or 2" long tube headers with Competition Only or GREEN connections, joining the 2-3/4" OEM rear interface after the specified factory exhaust cut.
SKUs: 2312H410, 2312H430, 2312H610, 2312H630
Choose the package around your LT4 build
Both primary sizes feed 3" collectors. GREEN supplies the catted choices suitable for the supercharged engine; Competition Only is the uncatted arrangement for competition use. The actual four combinations are shown with their SKUs below.
Retain a compatible rear system
The front connections are supplied with the headers and transition to 2-3/4" OEM outlets. Installation requires cutting the stock exhaust, so have that work planned alongside fitting and tuning rather than expecting a completely untouched rear installation.
