What aftermarket exhaust sounds best?

[Venomrain]

Yeah, my friends GT sounds brutal with his flowmasters. In my cobra acceleration is accompanied by a high-pitched burble that ends up becoming overwhelmed by the motor's high RMP song. In my friends GT the exhaust lets the passengers know it is there and working 100% of the time... irregardless of road noise, traffic condition or the 'occasional' 4k powershift. This last month I was tinkering with the stereo in my car (mach 460), and started to wonder why FoMoCo elected to put such a stereo in the mustang (I just learned the 2003 cobra will use a 1150 watt stereo. yikes). I mean, come on, 460 peak watts? That's almost too much. But then it donned on me: if I did get some killer exhaust setup I'll need the wattage just to hear some tunes lol. thanks for the advice 96GT
