Would be nice to include the post I had in the other thread before removing it, which is more specific than just "what is the best hfc for the G"....

Stil curious end of day which will give the least or no noise (if that's even possible), ie no hiss, rattling, etc. Seems like this is a common symptom of most HFC's...

^ I haven't heard any of these issues for HFCs, those issues are more common with Test Pipes.

Made a huge difference!


Yes, Berks are 200 cell (metallic substrate).
Berk used to offer 300 cell ceramic substrate, but I don't think they do any more.
Hey man,

Any sound clips? I have this setup on my Z and get significant rasp. I was thinking of swappint to Art pipes or XYZ pipe as a solution.

Curious how a clean sounding set up with Tanabe would sound like..

Helix HFC
I bought some Helix HFC for $200 and so far I like them way more then my stock cats but I wonder how come there aren't that many reviews on Helix HFC. I'm deciding whether or not to keep these Helix or go get me some Berks HFC...I think the Helix are 200 Cell just like the Berks.

no offense, but the poll is like voting for president based on popularity instead of platform...

The only opinions in the poll you should consider are those that have used more than one - and even then its flawed because no one has used them all.

So if everyone voted for XXX HFC, what does that do for you?

Edit - I didnt realize the thread topic was so old (dont know who bumped it, but whatever)... One good way to research any mod is to find articles or threads from multiple dynos (there are some dyno days that list different mods - but with the variables of combinations of mods its still hard to determine "best").

Quick noob question, is getting any sort of HFC pointless with an otherwise stock exhaust system? Will you get random hissing noises because of the diameter change between the HFC and the stock pipes? Thanks!

Yes^ I believe you do get the famous hissing sound when the rpm drops if you install HFC/test pipes and you probably will get rasp also at higher rpm if you install HFC/test pipe with stock exhaust. If you want less noise get HFC

I think they have one for the G37.
Hows the drone with these HFCs?

With my Fast Intentions exhaust drone was there but it wasn't bad

1. I always drive in manual mode so I shift around it

2. The exotic sound of the exhaust is so amazing I always got compliments especially when I started up the car at gas stations, grocery stores ...church etc

You just feel like you're driving something special
