This is an awesome exhaust, I have tried a few of the big brands and Graves is my favorite for performance and sound. Whole in europe, my race team mechanics told me that the graves map is the best they have ever seen; and they have dyno'd thousands of bikes with various exhausts. All that was really needed was some tweeking of the O2 levels to match my particular bike and location. A++++
