Hey guys so I have a 2017 V6 with the NPP exhaust option. I love the way it sounds but I've seen people talking about doing a secondary cat delete. I was wondering if anyone here has a secondary cat delete with the stock NPP and how it sounds. I know it shouldn't be a huge difference but just wondering what it does. Also, I think it keeps the option to quiet it down which I would like to keep. Is that true?
