At a bike cruise in a while back I heard a Kawasaki with an exhaust on it that sounded very deep/raspy/higher pitched/louder than my Yoshi on my GSXR. I fell in love with the sound of this pipe but I cannot remember the name of it. I believe it started with an M, H, or F.Sorry that is all the help I can give. But anyways, to the point. I want a louder/higher pitched exhaust than my Yoshi. I still want to keep my Yoshi but I want to be able to swap between these pipes depending on my mood of riding. So can you guys point me to a higher pitched/louder can? I was kinda thinking about a D&D but I've heard alot of people say they are annoying so maybe they don't sound good? Any help is needed.
