No7Yet

While I know that most of the noise you hear coming from a bike is intake and valvetrain noise, does anyone have any experience with an exhaust setup that emulates those frequencies most closely associated with high-strung sport bikes? I hear that note somewhere in my stock exhaust, I just need to know what mufflers (when combined with 3" piping and a Random Technologies high-flow cat) will most accurately reproduce that sound...

Any ideas?
