Really sorry for another hfc comparing thread, but I have only seem hks dual exhausts paired with berk until I came across the AAM hfc. I couldnt find any info on hks with aam, but a butt load of hks with berk. I was going to go with berk because so many people like their hks's with berks; louder and deeper sound. But I wanted to know if anyone would recommend aam hfc over berk. People said berk hfc sounds the loudest and sounds the best, what about aam? Does it sound louder than berk with hks? Please let me know, thanks.

 

Have you heard the Berk/HKS combo? If you like the way that it sounds then I wouldnt really question it just go ahead and do that route...I was very indecisive with my TPs and I finally just said screw it, so many ppl had gone the same route so I just followed that and Im pretty content with my choice!!

 

trust me man ,Berks gonna be loud enough

 

Just found this thread. The OP says that buying hfc is illegal, and it started in jan of this year. Is this true?

This is true for CA however I think you can still purchase them and use them for "off road" use.

 

So they are like test pipes and are illegal to even have them on the car, whether they are carb legal or not?
