CTS V owners I’m reaching out to you to determine what is the best exhaust to purchase in your opinion. I just newly purchased a 2017 CTS V that is completely stock and wanted to add headers back complete exhaust. I like to hear the exhaust sound but don’t want a lot of droning for longer trips. What suggestions would you guys offer? The car stock is to quite for my taste. Please let me know what you have or would recommend.
