I am sorry but I think ALL three option on the exhaust you photoshopped disrupt the flow and styling of the America. I think the exhaust you have on it looks better than any of the options you picked. Since you like the matt black I would think you would either like a short pipe or a Sceptre exhaust, or some other kind of slash cut pipe. If you want more rumble remove the baffles from the exhaust that is on it. But you will probably have to change out the jets if you do.
I have sceptres on mine and 55 main jets, and pods. I love the sound.
