exhaust cutouts, worth it?

i have the cut outs set up on my car. i have yet to start the car but i have this vision of me on the highway racing some douche bag in a mustang or some rice rocket at about 1/2 - 3/4 throttle pacing them, then hitting the switch and flooring it. the noise and then me just putting about 10 cars on em would make them wonder what the hell just happened for a loooooong time.
