I had several people ask me how the system sounded on the interstate I think it sounds just fine, unfortunately I can't get the greatest quality video on an iPhone from the passenger seat! (Thank to my daughter for trying her best) There is considerably more wind noise in the video than there is in real life! But I think it's good enough to get the point, I did hit at least 70 miles per hour... & I don't exactly have a quiet exhaust!
