Finish your CTS-V header upgrade with the right crossover
Join your Kooks long tube headers to the rear exhaust on your LSA-powered CTS-V with a matching stainless X-pipe. Choose Competition Only, GREEN or H.O. GREEN connections, all using the 2-1/2" OEM rear interface for the 2009-2015 car.
SKUs: 23113100, 23113300, 23113400
Choose the catalyst for your supercharged build
GREEN and H.O. GREEN give you two catted choices suited to forced induction. Competition Only supplies the uncatted arrangement for competition use. These are the front connections for Kooks long tube headers; the headers are purchased separately.
Keep your factory rear exhaust
The 3" front pipework transitions to 2-1/2" outlets for the OEM rear exhaust. Installation requires cutting the stock exhaust, then joining the new X-pipe to the rear section. You can change the front pipework and catalyst arrangement while keeping your existing mufflers.
