Berk, Kinetix and FI will all sound very similar. Berk is a touch smoother, Kinetix a little raspy and the FI has the best all around sound. Remember though that the overall exhaust sound is determined by the sum of all components involved. All will rasp some if added to a totally stock exhaust. Adding an air intake changes the equation again, different mid-pipes produce different sounds and so on.

If you want the best of the best, ART pipes rule all these three but they're officially test pipes and the price is fairly high unless you can get a used set but worth every penny.

 

I do have a cai but my exhaust is currently stock with deleted mufflers. I wish i could go art pipes but im trying to pass smog, so im going to try berk and if they give out in a couple thousand miles then ill remember blue dreams told me so. Maybe after a tune the life on the hfc can be longer but i will not do that untill i get an exhaust system.

 

I specifically meant their control arms, not the HFC. I also haven't heard great things about Kinetix's HFC. Upper A arm and lower rear camber arms have worked great for me. Godspeed feels Chinesium.

 

Chinesium..... well i guess the less you pay the more china it is.
