Road Noise? What's that?

I have a performance exhaust and you don't hear road noise, and with a touch of the pedal - I can't hear my wife beside me either .

I did RAammat and ensolite to try and deaden some exhaust noise. But what it really did was kill vibrations (pounding sub) and silenced the stereo outside the car. I can crank it to the max and just barely hear it outside the car with the doors closed. When I open the doors you can hear it almost a block away.

I'm sure though with a stock exhaust, a few layers of mat and foam will do a nice job cuting down on road noise.
