I really find that sentence funny. See and hear In my mind, an exhaust is all about power. More and how much and etc. Sound should be secondary, except that you do want it to be to noisy or have a drone. IOW, sound and power is a tradeoff, with power coming in first.I wish there could be a side by side comparo between a Borla equipped car and Joe Z'd car, to see and hear which is better.
