Upgrade the front exhaust on your supercharged CTS-V
Make the most of your CTS-V's supercharged LSA with a matched long tube header upgrade. Choose 1-7/8" or 2" primaries, both with 3" outlets for the required Kooks connection pipes.
SKUs: 23112400, 23112600
Choose the primary for your setup
Both stainless options cover the 2009-2015 supercharged 6.2-litre LSA car. Choose the tube size around your engine modifications and finished exhaust.
O2 extensions included
Both SKUs include an O2 extension-harness kit covering two front and two rear sensors. Add the matching Kooks connection arrangement to complete the front system; the headers do not connect directly to the OEM exhaust.
