I have the ATAK with ARH long tube headers, and really expected it to be louder than it is. But that's ok. As far as drone goes I really don't notice much drone inside the car. I hear the exhaust note, because it's louder, but I don't hear much resonance ( so called drone sound). The wife and I can still have a normal conversation at highway speeds. At wide open throttle it sounds awesome!

Don't quote me on this, but the performance gain, I believe was stated by Borla to be between 3% and 7% increase with the catback system. I still have yet to see an actual dyno chart of this claim though.
