It wasen't a matter of being louder, because they where Honda Gold Wings and what not. (Honda's and Yamaha's) It was the fact that here I am crusing about 50/55 and they didn't care, they pulled out anyway. I scared the hell out of last guy that pulled out because I did slow down of course, but I was right on his a**. He looked in his side view mirror and got on the throttle pretty good.
