Might be putting the cart before the horse here since I won't have my car for a while, but anyone know of any systems out there under development yet? I LOVE the sound of the Corsa system on the 2012 GT500 that I've heard on the YouTube video. That would be my first choice (assuming it makes power/cuts weight and looks as good as the factory set-up). However, I am open to other ideas that aren't insanely priced. It must have quad tips, a nice tone with no highway drone whatsoever, and absolutely cannot sound like some redneck with straight pipes. Nothing worse than drawing too much negative attention every time you leave an intersection.
