Bring a matched Kooks upgrade to your first-generation CTS-V
Upgrade your CTS-V with 1-7/8" stainless long tube headers and matching front connections. Choose Competition Only or Performance cats, both joining the factory resonator through the 2-1/2" OEM interface. Gaskets and installation hardware are included.
SKUs: 2310H410, 2310H420
Keep the factory resonator connection
The headers use 3" collectors, and the supplied pipes transition to the 2-1/2" OEM rear joint at the factory resonator. That gives the first-generation CTS-V its specific connection arrangement while retaining a compatible rear system.
Choose for the LS6 or LS2 build
The kit covers the 5.7-litre LS6 in 2004-2005 and the 6.0-litre LS2 in 2006-2007. Performance cats are for naturally aspirated use. Competition Only is the uncatted choice for competition use.
