When the engine is under load, it creates more exhaust velocity. MUCH more! Also, if you let the car warm up a while to operating temp, and you have the cat removed, you should hear it whistle a little. Mine does once its warm. It still wont be as loud of a whistle or a hiss that it makes when you're on the road getting on it.
