Dual confusion

[sjlawr]

I know there are a lot of posts on here about dual exhaust. But, i have a few questions. Does anyone have any idea where to get a tru dual exhuast system for a 2001 mustang V6. I am aware that take off gt exhausts are available, but what about the rear bumper cut outs? also, if i do choose the take off system, what mufflers do you recomend for a nice muscle car sound. I saw that flowmaster has a nice dual system for my car, but i don;t know if it is true dual or not. Any links to sites that sell true dual kits would be greatly appreciated. Thank you.
