I just installed the berk downpipe this week. The turbo noise is exponentially louder with the windows down. With the windows up there is zero droning and stays fairly quiet. I have this paired up with the stock exhaust.

I can feel the increase in power and especially torque. Top end feels much better as well. I am aslo running the JB3 with 4.5 lbs of boost over stock.
