I know this is a dead post, but I just installed my Berk's HFC's testerday.....To say the least, I am dissapointed. Seems like I gained a little bit of low end power......but the rasp is embarrassing. I have Stillen G3 intakes (dont think they would effect this), and the Stillen CBE. It sounded great before the new cats, but like all of us I wanted more power.......When the RAsp is not there, it sounds much more agressive, in a good way. When the RASP is there, all i hear is a coffee can civic, but unfortunately, its my Z.
