Does Anyone have any info on which is the better HFC to go with? I'm stuck between the berk hfc and fast intentions hfc. If fast intentions is the better of the 2 does anyone know where I can find them? Also I have a set of test pipes I never had installed yet either. Should I just do away with the HFC and use those even tho they are not resonated? If u can't tell...I'm not really sure as to which direction to go with. I have borla exhaust installed already, and borla headers that'll prolly get I stalled same time as the HFC or test pipes

 

Have you looked at the Motordyne ART pipes yet?

 

No. Never heard of them. They any good? ART pipes? Are they still cats or special kind test pipes?

Is there a big difference between Berks HFCs and FIs HFCs other than price?

 

There has been a few debates already with Berk and FI. Search and you will find

Stick with the original
Fast intentions

 

Right now I just have full borla catback exhaust (with stock cats), and intake. Some minor breather mods. I havent installed my borla headers or the test pipes yet...but Is it even really worth installing any of these HFC of these on an NA car?

 

I have read reports of problems with the Berk HFC (plugged, falling apart, etc).
