distance doesn't really create back pressure in a well designed/proper exhaust. pipe provides so little backpressure that i don't see that point in having 1 foot exhaust when an extra 9 feet of pipe doesn't really take that much away aside from directly the noise behind you. It would suck dick to travel any distance in that car, no music, no talking without yelling, criusing at highway speeds maybe around 3000rpm it would suck dick, you would loose your hearing.
