I have had the Berk HFCs for six months and really like the mid-range growl under acceleration. You can feel the power increase and from what I have read the gains range from 15-20 hp (without a CBE). When you are cruising there really isn't much difference compared to stock. I do not hear any hiss at all from them. I added the Invidia Gemini's and really didn't like the increased volume and the low frequency sound (to me it sounded artificial). And it does drone at around 2000 rpms especially in 6th. Removed them and sold them to Bluestyle55 who really likes them but doesn't have the HFcs on yet.
