I have Berk HFC and stock Nismo exhaust. Rasp is gone but I have a rattle, not a rasp, at 2 k rpm on decel. But it's not loud and when I'm driving I can't hear it. If I'm in the garage with windows down I can hear it. It comes from the back of the h pipe. It's some weird resonance with the heat shield. Next oil change I'll have the tech poke around and see if they can bend it. Oh if you have an intake and HFC you really need a tune.
