Out of the ordinary muffler question...

[Phantom5oh]

Ok I'm lookin to get a new cat back system for my stang, the problem is I want to get a quiet system. I'm actually looking for the quietest idle and cruising sound I can get, but with a little rumble when I lay into it. The car is a sleeper and the flowmaster sound is the only hint that it has any balls. I'm not looking to go any quieter than an stock GT or Cobra, but I don't want to buy stock mufflers, they are too restrictive. Does anyone have any opinions on what I should get? Price is a factor.
