Even though I have the Berks, they made the car sound so much better. Under 3,000 rpm, it is almost stock but it opens up after that point. After 5k rpm, the volume level is doubled or even tripled compared to stock and my opinion on high flow cats and the sound they produce is that this should be the way the 370Z sounds stock.
