Does FI CBE have any drone or rasp?

You only get rasp when you switch out the stock cats with high flow ones. I had Berk, and then switched back to stock because of rasp (when given a good amount of throttle) and loudness.

The 12" one drones quite a bit after a long hot drive, and it's between 2k-3k RPM as others described. Past 3k to redline it is very quiet. At idle after warming up it burbles, and it sounds pretty freaking cool

The video below was when I had the Berks, so you can hear what the rasp is like:

I fixed a decent bit of the drone with some custom side branch resonators. No impedence to flow and it negates quite a bit of it. Not many people want to weld onto their FI exhaust though but I didnt care since mine was custom made (and mucho cheaper).
