Need Help Buying the Right HFC

FernDiggidy

Hello Folks,

First time poster here so apologies if any of this sounds ignorant but I do need some insight. I've caught the mod bug, very badly in fact. I have a 2014 370z (base model) and I've been upgrading it for about a year now.

I have:

• Stillen cold air intakes gen 3
• armytrix cat back exhaust (I know it was pricey and I could have went with a cheaper option but I do enjoy the sound. Having said that, after some research I should have went with the AAM R-Line 3 True Dual Exhaust system)
• stillen headers
• z1 performance upper intake manifold mod

Now I need help choosing the right high flow cat. I wanted to go with stillen but unfortunately they discontinued making high flows and headers. I know I should have gotten my HFCs sooner but I didn't. I have searched the web profusely for them and although some sites have them on their online inventory, when I call they tell me that it is an error and that they are out of stock currently.

My next option is to either dish out more money on ebay for those same stillen HFCs or go with another brand that has great quality. Reading up a little bit on this and Berk HFCs come up.

Is this a good purchase for me? Is it ok to have so many mixed and matched parts in my build? Will there be any fitment issues between the stillen headers and the berk (or other) HFCs? (**Straight pipe or long tube headers are NOT an option for me**)

I have not had my car tuned or up on a dyno yet because I'm waiting on this last piece to do so. I'm anticipating something around 335 - 350 at the rear wheels after everything is installed and tuned.
I plan on getting new calipers and rotors as well as a new suspension later on this year. But for now I need some advice on where to go for my HFCs. Berk, AAM, Fast intentions etc....which brand will give me the best bang for my buck?

Any tips would be greatly appreciated!

Cheers

Fast Intentions HFC's are what you need. Your rear wheel HP are way to high. Expect around 315 to 320hp (maybe lower) at the wheels.

Ive seen alot of praises on berk and fast intentions hfc's. I plan on going with art pipes when I get my z. I had hfc on my 300zxtt years ago as well as on my sentra spec v and now i live in area with no emissions testing so I think im gonna go the test pipe route. Never had test pipes before.

When I was in the market for hfc's I read up on berk and some complained about it throwing a codes.

Go with fast intentions hfc's and you won't be disappointed. Sounds good, power gains and they never threw a code.

I bought Fast Intentions myself and got them in a few days ago. I stumbled across one instance where as set of FI RHFC's failed due to not being attached to a brace on the G37 forum. Any failures being reported here? You'd think, for the cost, they'd come with the proper tabs to attach to the stock brace.

As many of the options have been out for a while now, I'd love to hear more about long term durability.

Berk HFC have worked well for me, had them on for well over a year now and they did come with a brace tab, no issues other than the occasional SES light when I am driving long distances at a consistent speed, 50+ miles of highway.

I installed mine first when my stock CBE was on and they even gave a lot deeper sound, definitely no complaints and am happy with my purchase, fitment was spot on to stock and when I installed the FI exhaust they were sturdy and didnt look too bad for a year old Cat in the Chicago weather and even fit well onto the FI.

These have about 10k miles on them. Never gave me any issues.

Maybe it was indeed a fluke. I may look at installing some sort of bracing regardless. Just seems like they should come with a mounting bracket regardless.

Here's the failure, post #341.

On the next page, a member named Rochester tabbed up a bracket for the FI RHFC's.

I also have Berks hfcs non resonated ones and they have been great no problems either or no check engine lights on. I had them installed for about a year now also.

Folks thank you so much! I'm going to go with the Fast intentions HFCs!

Stillen headers and gen 3 cold air intake + z1 upper intake manifold mod + FI HFCs + Armytrix CBE! This setup is going to be LOOOOUD! I'll post a video as soon as I get it up on the dyno

Wait time for FI is a killer, but so worth it!
