Flowmaster Cat Back - Force II or American Thunder?

[06Stang]

Well, Ive been all around the exhaust spectrum the last couple weeks, but I think Ive finally decided on a Flowmaster cat back, but which one? I dont want an extremely loud one, but want you to be able to hear it if I drive by. I also dont want to have to scream to hear somebody talking inside, so which do you think would be better for me? I had a single in/dual out original 40 series turned down on my 02 GMC and it got pretty annoying, but I figured having 2 mufflers and them exiting in the back it wouldnt be as loud in the Mustang. What do yall think?

ps - also, does anybody have the Force II system? how loud is it compared w/ the factory system, or even a magnaflow system? also, ill be leaving my factory H and manifolds on for now, so keep that in mind as far as noise levels go! Thanks in advance for the help.
