Best HFC for GTHaus CBE?
 

Berk hfc are usually preferred around here. They have a 200 cel count I think, don't quote me lol any hfc will fit any exhaust due to all the parts are meant to fit with any part. Erz are pretty good but it really depends if you want rasp or not. Check out some videos on YouTube, that should help you get a better perspective on how loud the difference between the two should be. But as far as cel count I believe that the lower count the less restriction and therefore the louder the sound. Hopefully some of our fellow Z drivers can help you out. Good luck bud! :tiphat:

Ya i want the loud growl from GTHause thats why i got em, but I dont want it to sound like a riced out honda...I understand rasp breaks at some outrageous certain points and thats ok. also I heard almost all give 4-6 hp so why pay more? either way thnx Gibby. any more advice members PLEASE?!?!

Get a resonated HFC. ARK and Fast Intentions makes them. ARK won't fit an AT though.

I was going to recommend those hfc but due to the fact that he wants the exhaust to be as loud as possible I recommended the berk. But yes the ARK resonated hfc are going to give you more power but will not make the exhaust as loud as it can be, but they will give you more power (they only fit standard 370s). Like I said, it's all preference bro and to find the hfc that fits your needs. They're all gonna give you different sound, rasp, and power gains.

I only recommended them because he didn't want rasp. With an exhaust like the GThaus, there isn't much to clean the tone. The loudest exhausts will always sound raspy. With long tube headers, a HFC and a 92db rated exhaust, my car is loud under throttle. Uncorking HFC's on a loud exhaust with a convertible may become overwhelming. The GThaus is loud as hell with the stock cats. I would venture to say it would easily be over 103db.

Have you gotten your Z back yet??? I can imagine how anxious you're getting haha

Nope. Still waiting for them to start. I won't be able to drive it until August...

Ya I got AT so I guess ARK is out :/ any thoughts about Stillen or Magnaflow? Uncorking is punching out the Cat right? And big if, If I did F.I. LTH, that just bypasses cats and goes to the mid pipe right? Good advise so far guys thank u.

LTH doesn't allow hfc to be installed so yea. But plus side is that it'll give you more power than any other set up and it'll give the exhaust a nice sound.

So how do u work around the O2 sensors if u run st8 LTH? Won't that just mess up the car in the long run?

Lols. Has anyone run Gthaus with LTH?

I say do it. That'll be so loud you'll be heard from space.


Tapatalk & such etc

Car won't be messed up with headers or test pipes. There is usually a bung that is attached to the testpipe or LTH. It pushes the O2 sensors away from the exhaust stream.

@Asdfsammich I really couldn't stop laughing right meow. Lol that's funny. It's really what I want as long as the LTH doesn't cause problems and I can slap em off and on in case I needa take it in for warranty. That's the whole reason why I'm even debating getting HFC bc that'll void it too! But I mean another grand just for pipes is a lot of money! Just dropped 2,500 for the Hause!?!

yes someone has already ran LTH with this catback. make sure you get videos OP the sound never gets old.

I just purchased some Fast Intention Resonated HFCs :D. In the G community they are as good as it gets: No drone, deeper tone, good gains.

Get resonated whatever you get. I have GTHaus CBE and unless you resonate it's going to be louder than you want. Even if you like loud.

@ZKraken22 Do you have a link to the video? I would love to hear it before investing another grand. Thanks

@Gauge got a vid? This I gotta see! I want the loud roar of a giant testicle Lion on a killing spree with bazookas attached to his cyborg tail! @SgtGoldy how do u feel about Resonated Test Pipes vs R-HFC? i mean its half the price IMO.

Nismo 370z berk TP Meisterschaft exhaust - YouTube

My Motordyne ART pipes get here Wednesday. AFAIK I will be the first to mix the two. I'll post a video once I get them installed.

IMO the above video shows how TP's ruin the great sound our exhaust has. I'm hoping ART pipes limit this to a degree.

@Gauge thank u so much!!! I've been looking for TP or LTH on our GTH CBE. so i guess I'm just gonna go ahead and get a Stillen oil cooler for the time being untill next fall season. Just looked up those ART pipes and damnnnnnn those read badass! I mean u just gotta grab a good vid of em once u slap em on.

OMG that's loud

Best bet is resonated HFC's or RTP's. Especially after hearing that clip. Sounded like a roaring Lion screaming in pain while he's getting nurtured without any anesthesia. I would even caution against LTH's because they will rasp without good resonators and mufflers to smoothen it out.

^This. I have the ARK hfc and I have absolutely no rasp on my non-resonated exhaust. I think the ARK's are currently the best cats available if you don't want rasp

idk man... My buddy purchased some Fast Intentions Resonated HFC and they have zero drone and zero rasp. Made me decide to buy some (and I wasn't even looking to touch my exhaust system)

Fast Intentions 370z Resonated High Flow Cat

I am in the same both but will choose the FI RHFC, i had those on my previous catback and only added a slightly deeper more beautiful tone to my FI exhaust. Next my friend with MXP tried a handful of cats and all were raspy and the only ones that sounded best paired with MXP were the FI RHFC.

I'm still waiting to hear the ARK's. those are gonna be interesting

Anybody have ART's installed?

Berk.

NYbladez had F.I long tube headers with the Meisterschaft he loved it. maybe PM him and ask for a vid

Yes please do post video :)
