Really considering these headers with their HFC's and the FI 18" CBE. Would love to just have the FI LTH'S and CBE but knowing my luck I would get caught for emissions here in IL. Hopefully with this set-up I would be relatively close to what the performance gains would be with the FI LTH'S and CBE.

Got back from vacation to work today, car is still on the lift but the headers are on, just waiting for the o2s, supposed to be here tomorrow. I wish I would have done side by side photos of these, cannot believe the horrible design of the oe headers, the pipes are flattened in places and the collectors are so restrictive IMO, just wow, tubular but total fail...

Joe, when you get a chance, if it's not too much to ask could you forward me the total cost of your install. I'm looking at these as an option in the future, and I'm trying to look at labor costs along with purchase costs.

:tiphat:

I paid a tech at work under the table, motors guide pays about 7 hours for the job, most shops depending on labor rate will be between 600-800 unless they do not know what they are getting into, I asked him today if he would be willing to do more sets for anyone local and he has no issue with it, he is a young guy with a mod addiction as well, but he is a honda guy :( HOWEVER he has one of the cleanest and tasteful civics you will ever see...He is a training master tech in the honda PACT program, one of few young people that are not a total f5^k up these days...I applaud him for it, thus why I trusted him to do it. He did it for $250 bucks(he though 300 would have been fair, but I got the co worker discount), word of the wise, prepare for o2 sensors, the thread ripped right off them and there is only 20k on my car, ans he soaked them in blaster overnight and used some heat, no one in the shop was expecting that, myself included, we pull sensors out of high mileage honda exhausts all day long.

I mentioned it in my review of my long tubes a while back that there is a chance they won't make it. $300 is waaaaaay cheap.

Thats understandable. I wonder if the fact that mine have already been pulled from the OEM headers and put into long tubes will make them easier to remove... :confused:

I am so disappointed that it'll be awhile for mine being installed along with the aam test pipes and a retune. I will relocate to tx on the 27th so I so as quickly as I can get em installed it will be done

The thread bungs ripped off both of my OEM manifolds too....what a joke. They are basically just spot welded on.

Give you guys a tip when installing the O2 sensors. Use lots of nickel anti-seize on the threads of the sensor. BUT keep the stuff off of the sensor section. ;)

The new ones came with anti sieze on it, image that. The new sound of this car about 3k is :happydance: I want to eventually get soem art pipes to take care of the rasp from the test pipes at about 2500, but I just wanted the car back on the road.

First mod I have done that I can say there is a "noticable" power bump, this car pulls hard up top now, really hard. I threw z1 test pipes on there just to get the car on the road, but I ordered up some ART pipes, the rasp at 2500 rpm is nasty, cannot wait to get tuned. With a tune I can tell you from my experience we are in newer mustang 5.0 gt territory(know a guy with exhaust/intake/reflash) should hit the track with him next week.

Be sure you get 350Z DE art pipes...

so...these will only fit,with 350z hfc's and test pipes? so my berk hfcs wouldnt work..

thats is correct..the Berk HFC will not work untill they change the flange type

Alright thanks. Just wanted to be totally clear on that.

now,im not a master with headers...but wouldnt it still be better to just get long tube headers? Or are these just that much better?

No one has done a true comparison to the PPE LTH.

I can tell you with some certainty that they will perform better than the FI LTH though.

350Z DE pipes. Gotta remember folks that there is an HR 350z too that uses the same flange as us. Those will not work!

Hopefully, like it's been said before, they will bring out the headers with a 370Z specific flanges so we can use them with 370Z parts. One day...

I hate your face. :inoutroflpuke: :bowrofl:


:p

No options for cats and or test pipes, I am going to run ART pipes, and if I needed to or sold the car, the headers could stay on and I can slap the cats back on.

This will fit the 370z art pipes right? I know they are a copy cat of the momentum headers didnt know if you had to use 350 art pipes instead

These can use nothing 370z they have de engine flanges

You will have to buy All ART pipes, Test Pipes, or HFCs that were made for a VQ35DE (03-06 350Z). They will not work with 370Z cat pipes or replacements.


Which is funny considering a 350Z HFC will still mount up to a 370Z exhaust Y pipe... :icon17: Go figure...

yup literally everything is the same minus the 3 bolt (triangle) flange that switches up from the DE and HR

Then what's the point of making 370z headers if they don't work with other 370z parts? Seems like they are 350z headers not 370z ones.

Because they are, they're exact replicas of Momentums 350z headers :)

I guess you've missed the hubub about these headers?

They're yielding far more gains than any other shorty and more than some longtubes. That's why people are using them.

You just need the proper test pipes and HFC to go with them.

Oh Nissan why did you have to change flanges??? :( The difference is so small!

Any more dyno numbers coming soon?

Definitely going to wait on these until they come out with the HR flanges but from what I've heard this will cost an additional $150-$200 from the existing price from speaking with Jon at Z1. That's fine though since I would rather have either the HFC's or Test Pipes that are made for the 370Z. Hopefully it won't be too long before the HR version comes out.

You understand that it's just pipe with flanges on it, right?

There's nothing about them that make them better suited to a 370Z over a 350.

If they hadn't changed the flange (I suspect to allow mounting a larger/different catalytic converter), they would literally be the same parts for the 2004 350Z through the current 370Z.

I know that but seems silly not to offer different flanges for the guys who already has art pipes for the 370 like I have and others that have done hfc or test pipes etc

Yeah, it's kind of a bummer if you already have TP/HFC/ART Pipes.

You could find a buyer easily for your ART pipes, though.

Just an option since it sounds like the headers with the "correct" flange on them will cost more than the current version, meaning you'll still end up paying more than you would if you sold your 370z ART pipes and bought the 350z ART pipes.

Yes I do realize this as its been mentioned quite a bit in this thread. I would just rather use the HFC's or Test Pipes that are specifically made for the 370Z because I am looking at specific companies for one or the other. I do not want to use their HFC's or Test Pipes. I am not planning on making any of these changes to my car until early next spring when I'll be getting my FI CBE so waiting is not an issue for me.

.... again, you realize it's just metal pipes with flanges, right? No magic, no mojo, nothing special about them.

Most (90+% or so) companies that make a TP or HFC for the 370 make one for the 350. The piping diameters will be the same, the cats will be the same, only difference is the flange.

You will pay MORE for no difference at all in performance or fitment. That's my point, they work the same...you will pay more... for absolutely no reason what so ever.

yeah only diff between 350z and 370z is the flanges.

Also, most companies that make the 370z hfc or test pipes also make them for the 350z so you could still get the company you want. But some advice, just get the z1 HFC or z1 TP. You'll save money and get a quality product.

Agreed, unless you want resonated TP's or ART pipes or some other fancy pants thing. :P

I want the 370Z flange not only bc I have the ART pipes already, but bc I can easily swap to my OEM cats when inspection comes. Don't want to bother looking for DE cats.

I feel like we're starting to beat this horse to death already

Anyone else?

I know exactly what you are saying and I have looked into that as an option. I realize that companies do have DE versions of HFC's and TP's however as I mentioned I am not going to be buying these any time in the near future. I'm not in a rush to get this done so possibly by the time I am the headers specifically for the 370Z may be available and I would just go with them then. If I was in a hurry or wanted to do it right away then I probably would go and purchase these.
