^I agree with Chris, the length thing is people not knowing how to GOOGLE something...

Still hate the flange

You know what kinda bugs me....

The fact that Z1 has not jumped in on the discussion..:shakes head:

Geez go sell one of the families oil fields and buy the damn test pipes......sheesh lol. You're spending $850 on headers without install. I think you can spring the extra $150. For those that want ART pipes, there's always a butt ton for sale on the the 350 and g35 forums that you could actually probably make profit off of it.

I want my manifold back, SOB

:icon18: Good luck with that! I bet some people on the forum probably think we hate each other :rofl2:

I'm gonna sell a god damn oil field and fly to Hawaii and steal the damn thing off your car, LOL

Anyone think the car will pass CA smog if I swap to stock DE cats + these headers when the time comes?

I feel it would be cheaper for you to just buy another stock HR manifold and make your own again lol

Z1 headers were built in the same jig as the Momentums.

Question? If the flange was made for the 370. Would you pay lets say $200 more? I feel there's a bunch of excuses for not buying now that there ready. People talk till the money is ready to be spent. This is modding.

:iagree:

I also think its kind of funny that a lot of guys complaining about that de flange.... its a copy and not a modification of the copy . I havent read anywhere where they said they would install the hr/vhr flange . As far as making money well they are a bussiness to make money ... right now even with the inequal colleclor lenght that piss me of in a header design is I dont see anything that are or will be available for the low price Z1 are selling those. The cheated bent that can clearly be seen is another point but slightly less critical than the collector.

But overall they should/will perform better that any available shorty header ( stillen as exemple.... )
On a side note equal lenght primary tube does not alway mean they are true same lenght. There is up to a certain lenght that is relatively acceptable for primary ( 1+- inch) and should not be like 3 inch !!!

FINALLY :) Now to place some orders

I'm confused... are there really significant gains to be made with a shorty header? The stock manifolds are pretty much shorty headers already. Is it the collector that's supposed to make the improvement?

I understand going with long tubes, but shorties? I'm not seeing any real gains to be made here.

The flange is the reason why I'm out, to ME it makes no sense to spend that much money and make something work. It is awsome that these headers finally came out with proven numbers and name. I still feel that it is a useless part for me vehicle.

Well the Momentum proved to give some really great gain ALONE and with an already fully modded vehicule . Those Z1 should be very similar to the potential of the Momentum..
But we have yet to have seen a comparaison back to back with a known LTH.

I bought from a friend not long ago a pair of those momentum but my testing **Momentum Vs PPE) wont be with the VHR engine anymore . Since my Z now has an 3.7 stroked HR (3.5).


You cant compare our oem shorty header against the z1 &Momentum.
Yes the collector play a very big role to gain power but its also everything that will help to acheive those gain.

All this crying about price and this being a waste of time over buying other shorty's DESIGNED specifically for a 370z is a joke.

Lets play devils advocate and use a Stillen set up as an example. Their headers are $695 w/ t304 stainless steel. Z1 is offering their Momentum clone headers at $895 and for $1033 you get test pipes as well. Add 370z test pipes ($269) to the Stillen headers and you are at $964. You are telling me you would rather save $69 to make less power? If you are going through the effort of installing headers on a 370z you might as well do it right as it is very labor intensive. I could see if you already have 370z HFC or TP being somewhat disappointed as you will have to sell your current hardware.. but I am sure they will sell fast on the forums here for a large percentage of what you paid.

Lets not forget barring a few sets that were dumped when momentum was firesaling inventory they sold these headers for $1,299.

I think you guys should be happy z1 has managed to secure the jig, do R&D, and release this setup for an affordable price. And if you still have stock cats the additional $69 dollars price difference over a very nice set of headers from stillen (that make less power) is a steal. We all know you can throw money at these cars to make NA power but $69 is an oil change for these cars.

*all prices taken from z1 website.

^well said

Well that's what I want to know; what does the "everything" entail? Are the primaries larger and/or longer than OEM? Is the collector a true merge?

I have a problem with this :mad:

Sorry John I was just messing around! Great job getting the headers done for all us VHR vultures :tup:

I am not trying to get in a pissing match with you. With the flange being different why get rid of parts you already have just to make something work. Im stuck with over 2Gs of parts for a KA24DE that I cant get rid of because I tried to make something work. Why get rid of something that is already there or bought. I agree with you as I have stated it is awesome that the headers are here.
Also as stated they are going to come out with a different flange so it is not a big deal, as stated by John "Be patient as we will have the 370Z flange soon".

I did not mean to single you out. It was meant to be for the whole thread. I have removed your quote from my post.

The whole why remove something that is already there or bought comment is easily answered. Because Racecar. When people switch to FI setups they have to replace some bolt ons they have already installed to accomplish those goals. If you want to wait for the 370z style flange then more power to you. Others who want to take advantage of the best bolt on power increases we have seen for this platform will want to go with the current setup now. I am assuming Z1 will not be able to keep the price as low on the 370z flange style headers due to additional R&D / increase in production costs for a separate inventory item. It will be interesting to see what they go for and if it is cost effective in the end vs using VQ35DE parts.

As far as the KA24DE parts you can't find anyone who wants to turbocharge their stock motor in a 240sx? I thought that was the FOTY for 240 guys?

If they came out with the 370z flange not one person complaining now would still buy. I see this all the time here. People want, want, want till the product comes then bail when it gets here. Everyone wanted the Momentum headers after they sold out and now you have the same exact thing and you complain about it. It's almost like waiting for tires (headers) to come out and complain they came with air instead of paying $20 extra for nitrogen (TP's).

Hope you people don't build a racecar. You'll be in a world of custom hurt.

Well to you sir, I have money set a side for this ever since the rumor started. Either I will go with these or get long tube headers. For the rest of your statement it is dead subject. Either wait for the flange and hope for the best or just buy the DE kit.

Please put my quoted comment back in your post, maybe someone when they search for this topic will laugh about the entire situation.

I think this thread was to give people the heads up on what Z1 was brining out for our members, and Thanks SPOHN

Now people have had plenty of opportunities to posts their concerns pro and cons

And it seem things have been made clear as to what people are buying.

A good setup in my opinion

As the OP, If SPOHN feels its run its course? He has the ability to close it.


Anymore squabbling, And I'll just close it myself. :ugh2:

Back on topic!

If it wasn't for me being in Cali having to worry about the sniff monster? I'd have a set :(

:icon23: :hello:

I don't see what they would have to laugh about... I apologized for quoting you and making a scapegoat out of your post. You just happened to be the most recent complaint. Please move on from this thread :gtfo2:. Thank you chris for posting this thread and enlightening the370.com masses. I am in the funding stage to pick these up and pair them with Motordyne art pipes + the Nismo OEM catback. I think it is going to sound perfect. Aggressive but not too loud.. If it is close to the 330whp mark the z1 mule car hit with Nismo exhaust I will be happy.

With stock cats or hfc, this should prob still pass the sniffer.... I think new cars in california dont need smog for 5 years? Im good for 4 years.

Damn you. I'm due in 4/15. I think I ll pass if I swap to stock cats too.

yea, the cali visual inspection will most likely NOT catch the shorty headers. stock cats should be do-able to pass smog alone. wish this had the 370z flange :(

Yea I'm gonna wait for the 370Z flange too. Too much hassle to look for stock DE cats when smog comes.

Someone else that doesn't see the sense. I guess the two of us be the onl y ones waiting.

i got a set of DE cats for free. Was one of the things I continually searched for as I knew eventually I would need em. Didn't expect to find them in less then 2 weeks lol

I'm going to give these a shot (I think) and I have my base dyno with:

AAM Cold air Intake (R-line 2 3/4)
AAM true dual 2.5 exhaust
Motordyne M370 intake manifold
AAM HFC
AAM Uprev tune

in the above configuration it's 317whp/266wtq

Replace the AAM HFC with Z1 HFC and add the Headers that report should occur in 2-3 weeks I guess maybe sooner depends. I have an email to z1 with a basic question and one to AAM with another basic question on cost/ etc..... we'll see

Nice, can't wait to see your results :)

Currently sold out but more in stock in about 2-4 weeks so this is a definitive go but with one change I'll be switching to TEST PIPES rather than HFC along with the headers. A nice tone change I'm sure ;). Anyway will be dropping off deposit on Wednesday sometime so they can be ordered and then it's anxiously wait and probably have another track day before they are installed, bummer but you never now could arrive quicker. soon as results are in they'll be posted.

Actually since AAM is doing the install I assume they'll probably post the results?

has anyone from the forum bought one of the first sets and had them dyno'd yet after their re-tune?

Dang they're sold out already? Glad I got mine early! :tup:
