I am personally running a Modified Concept 2.5" cat back with stock headers and cats. For what I paid (~$150), I am not complaining at all. It has a nice sound at idle and sounds awesome at WOT as well. I'll admit it is a bit droney on the freeway at cruising speed but nothing that a notch or two on the old volume knob can't fix.
Here's a video I took with my crappy point and shoot with it's horrible microphone. It doesn't do it justice at all but it's better than nothing.
