Hey guys, I wana get an exhaust system for my 2016 silverado 5.3 but I don't know what to look at so some advise would be nice. First I want louder than stock but not crazy loud where I wake up the whole neighborhood. In medium to aggressive. Second Im wondering if I need to get a cold air intake as well to pair with the exhaust or could I just do a performance air filter in the stock air box? I don't want to completely throw away my extended warranty. Any help would be appreciated. Thanks
