Give your supercharged CTS-V more to work with

The supercharged LSA makes your CTS-V special, and the front exhaust is a worthwhile part of a serious upgrade. These Kooks kits pair 1-7/8" long tube headers with an X-pipe that joins the factory rear exhaust. Choose GREEN cats or Competition Only pipes while keeping the rear system you already like.

SKUs: 2311H410, 2311H430

Headers and crossover supplied together

Both choices use 1-7/8" primaries, 3" collectors and a stainless steel X-pipe. The rear outlet reduces to the 2-1/2" OEM interface. Buying the pair as a kit gives you matching headers and front connections for the LSA conversion.

Fitting to the retained rear exhaust

The stock exhaust must be cut for installation, then the 2-1/2" outlets join the retained rear system. We recommend professional fitting so the cut, alignment and clearances are handled together.

Choose your configuration

SKU Configuration Supplied arrangement Fitting / engine conditions
2311H410 Cat Type: Competition Only Headers; Competition Only front connections Factory exhaust cut required; Uncatted; competition use
2311H430 Cat Type: GREEN Cats Headers; GREEN Cats front connections Factory exhaust cut required

Tuning for your exhaust upgrade

We recommend tuning with every header installation so the calibration suits your new headers, complete exhaust and fuel. Contact us to discuss the right tuning route for your vehicle.

Frequently asked questions

Can I keep the factory rear exhaust?

Yes. The X-pipe connects to its 2-1/2" interface after the required factory exhaust cut.

Are these for the later LT4 CTS-V?

These kits are for the 2009-2015 LSA car. The 2016-2019 LT4 CTS-V has a separate header-and-connection kit.
