First off...thanks for the replies and the suggestions....I decided to get the screamin eagle 4 inch cannons and let me tell you....it's perfect for what i needed. Low mean grumble like they were advertized and not annoying like my screamin eagle II's were. Even the guys at work said they like the sound of them better than the stock. I'm happy with my decision because my bike sounds like a harley and not a scooter. I can still hear my radio at speed and the sound is not overpowering at speed at well...a very low grumble.
