Lets start! i have a 2006 5AT g35 coupe and just got my 5/16 plenum spacer as a second mod (Jwt pop charger was 1st) now i want to get HFC as a 3rd mod, no test pipes and running with stock oem exhaust. I heard Berks HFC are pretty good any1 have any other suggestions? and experience any noticeable gains after installing it? thanks

 

Fast Intentions HFC's. I think you'll notice gains with any hfc.

I have the FI exhaust but just picked up a pair of berk HFC's on the recommendation of the guy that is doing my vortech install next month.

Got them for $399 shipped so not too bad.

 

FI HFC. You wont be sorry.

 

Berk HFCs because they have the Factory Mount which all others don't thats the ones i have and they're loud! make sure you buy gaskets for them.

 

I got the berks. Fitment and quality are excellent. They also make the stock exhaust sound nice if you dont like things super loud....It just makes it a little louder. You wont be dissappointed.

 

thx for all the replies but i decided im going to go with the Berks HFC's!

 

which cats have the least chance of cracking, berk or FI?

 

motordyne ART pipes!!

Berk Metallic HFC!

 

Motordyne ART pipes - better gains. better $$/HP investment without a doubt.
