Yep, night and day difference between now and right after the install of the HFC's. The rasp definitively got a lot less over time. I had Berk HFC's + Berk CBE myself for a while and that was a little raspy as well. It also was waaay too loud for me, so I got rid of the HFC's and went back to stock cats but I kept the Berk CBE. Now there is no rasp, just a nice deep tone.
