Most of the deep tone is between 3500 and 5000 rpm if your on it, then it smooths out a bit over 5000.

Cruising on street at 45mph - 4th gear = no drone, talk on your blue tooth, listen to stereo etc.
Cruising on Freeway, steady 70-80mph=same thing :-) it's pretty amazing!

Now that I've been driving with the Berk exhaust for a few days, I've really learned how to get the sound out of it, or not get it out. It's pretty easy to make it sound mellow if you shift at the right points, and also easy if you want to roll by a Mustang or a new Camero and make them wonder what the hell you have in that thing. :-) Also, there is no question that this has freed up some power, it is noticeable over my previous Nismo setup. The throttle response is better and the power comes on much sooner. I'm really enjoying the car again. I especially like it when driving through a tunnel or freeway underpass, just roll on the throttle lightly and it's music to the ears. Awesome!!
