Want to know what Kooks headers to stock mufflers sound like on a 2016-2019 CTS-V? Cold Start, Revving, Dyno Pull, Idle, Racing, Windows Down etc.
This is a compilation of videos to get a better idea of what Kooks 2x3 Longtube Headers with Catless Connection Pipes to Stock Mid Pipe and Stock Muffler sounds like. With the stock muffler, you retain the valves so you can open and close them but all the footage is with the OEM muffler valves open.
