Honestly man the Berk CBE without the HFC sounds almost like nothing, very quiet. When both paired up its sounds mean as hell. As far as the Fast Intentions 18", it sounds almost like the Berk with the HFC. Both exhausts without cats, the F.I. Sounds better. Berk HFC and CBE vs F.I. 18" I think is a toss up, both sound great. Now a F.I. and HFC should sound sick, but I've never heard that combo so can't really say but should be great.
As far as customer service, F.I. is the way to go. Also as Maclean said, there was a couple incidents that popped up involving the Berk parts, but I cant really go out and say its a bad product because there was never really a persistent issue with Berk and many people are happy with their Berk products.
