Fooling with exaust

I got bored and was fooling around with my exaust. I have always hated the sound of the NC's stock exaust, just not loud enough for my taste. I removed the exaust a few times, and without an exaust it was loud, deep and mean sounding. However, it vibrated like crazy and was so loud it scared people. So as an experiment, I stuck 2 washers between the flanges to see how loud it would be. To my surprise it sounded kinda nice. Ashame I can't keep it that way, but carbon monoxide is bad and it may be illegal to do in Japan. Here is a video of how it sounded. It's kinda long, was waiting for the dumb trains to pass by.
