This is truly the best exhaust system on the market. I love everything about it. It is quiet most of the time, it makes driving with it almost seem like there's nothing different about your upgrade. That is until you sink the pedal to the floorboard and the everything changes. It has a powerful sound and no drone. It has a killer look as well.
