Not gonna make any difference in power. Nothing exhaust-related will really help you power-wise right now, unless you ripped the whole thing off and did a full true-dual 2.25" or 2.5" exhaust complete with stock mustang 5.0 headers.
It will definitely be louder with a turndown thats for sure. Youll feel it shake through the floor. I like that a lot, not everyone does. Thats what you have think about, whether or not that's gonna annoy you lol.
