That's a great deal $350 shipped! There's some top speed's on EBAY for a decent price, but I'm hesitant to buy from there. I'd rather buy from the forums. Thanks 4 the input on the DC headers. Can anyone comment on the top speed headers for fitment/quality????

 

the fact you could get DCsport for 350$ shipped while they MSRP for 950$... is another hint that they are the same thing as top speed, megan racing, etc...

Made in China baby (which doesn't mean bad quality, just huge margins evidently)

 

the ss dc sport headers were mismarked on summit racing when i bought them a while back....not sure if the dc's are the same as the others you mention

 

I have the topspeed headers and am very impressed at the quality for the price. They had beautiful tig welding and fit was good. I coated mine with jet-hot 2000, so the total cost was around 400 bucks. NO OTHER HEADER OUT THERE CAN TOUCH THAT PRICE. Which is something to brag about since nexus and dc are the same design/flow.

My headers will be going up for sale soon - just got my aps TT kit and they need to come off. under 1000 miles on them. I have a blue Injen CAI that will be coming off as well. PM if interested.

 

Alot of you guys sit here arguing the facts about header designs, but the key HP isnt just the header piping design but its also a variation of the inner header collector transitions, alot of these cheap headers dont have a good sharp and smooth pyramid transitions and sometimes even just cut off and welded into a pressed collar to save cost and time. REAL proven gains were made with a set of JDM Escort Racing SS headers which cost the most ive seen but made the most gains. These hand made babies are $1900 bucks http://www.escort-us.com/products/z32/VQ35HDRB.JPG they had a guy dyno a 28hp gain off these puppies and all he had was a cat back and intake.

 

those look very nice. i have always been a huge advocate of a nice merged collecter. nismo, crawford, and brm all have this nice slow merge, and they all make good power. the DC clones (yes, everything we have been talking about here) all have the same style collector, where three tubes dump into a larger tube quickly, and have no real "merge".

the install is such a pain, i would do it right the first time.

 

If anyone wants some personal advice from someone who has seen the Alphawerks header in person and is a big member of this site as "reavtek" (who has 501 posts here) who came by our distribution center yesterday and was demonstrated some (although not all) of the design elements that seperate our headers from others...the following was his quote and this is the link to the post...hope to give some perspective on this they all look alike deal...take care guys...

<b>QUOTE:</b>
"Today I went over to the Alphawerks distribution center in Doral, FL hoping to get in on one of the sponsorships for their headers. First of all, they are a great buncha guys! Real car enthusiasts with a passion for everything automobiles. I spent almost an hour there chatting it up with one of the representatives. The sponsored cars are crazy! Definetly some stiff competition. Unfortunately, I didn't get the sponsorship I was looking for. I guess I just dont have enough crazy bling mods to set me apart... Who needs 5 amps anyways? :/ But, I still want to consider alphawerks headers. I saw the headers in person, let me just say, WOW! They look fantastic, excellent welds and beautifully polished. Anthony showed me the original JDM header and the new Alphawerks USDM redesign. One of the tubes was extended and the bend placed higher to clear the steering knuckle."

 

Also...I just went to notice something very interesting, in the pictures that everyone here is posting here of the Alphawerks as "identical" to another USDM header. That picture of the Alphawerks header is of the JDM Alphawerks header that wont even fit in your cars. It is just impossible for the headers to be the same if one fits the car and the other does not? Can't be the same header if one fits and the other one will not clear the steering knuckle on the drivers side of the car

We are doing a new website that will have all types of zooms and new pictures that will post the final product that is sold today hopefully this month.

what ever happened to those "lucky" folks who got the nexus sponsorships?

did nexus provide all of these folks with headers and dynos free of charge?

just curious....i subscribed to that thread and never did find out what the results were and what cars were chosen

lates

 

We sent out 5 headers 100% free of charge full sponsorships...plus 5 partial sponsorships to members of my350z.com and g35driver.com. All winners received a full color poly-satin shop banner and enough catalogs to shake a stick at...

Congrats to all the winners,

cool....thanks for the update

 

Yep I was picked, Ill give a full report once I get them. I also plan on doing a how to install these bad boys! Victor do you know if my set shipped yet? Its under Steve Norton with the Blue G35

 

what about us Canadian boys? One sponsorship up here could really boost your cross border sales given that under NAFTA we wouldn't pay duty on them.

I am happy to volunteer for the local 350Z/G35 club! Just a thought there Victor

 

Wow is that 28whp?! If so, I'd definetly consider throwing down $2000. Is there any kind of guarantee that if the gains are not realized the headers can be refunded? They certainly look fantastic.

The Alphawerks unit is, most definetly, one of the best (if not the best) inexpensive header on the market. Pictures definetly don't do it justice. The welds are impeccable, very clean and perfectly done. Some of the best welds I've seen are on Tanabe products and Alphawerks has some of the same high quality welds. The bends look very smooth and gradual (the sheer amount of welds makes it look more angular than it really is). The part where nexus is messing up is the dynos and the photos. We need current, up to date photos, more angles and larger. As for the dyno... Why dyno with a car with 20" wheels? I dont think this is a realistic setup and is actually hurting gains. The performance conscience 350z owner uses 17s or 18s.

 

The 20" wheel 350Z dyno'd 14rwhp...which is the lowest i've seen, I think they throw variables in such as a hot day, 20" wheels, etc. to show you that these headers DO make good power.

 

out of all the headers out there i would probably go crawford or alphaworks...but since i got such a good deal on the dc's i couldn't pass up the opportunity. i am very happy with the performance of the dc's....smooth gains throughout the powerband.

i wish i had the access and the money to dyno my car each time i added something to see what the gains would be. i think a lot of people put to much emphasis on dyno's here when they start comparing their results to other peoples or even manufacturers results (which imo are biased). i understand that people want numbers but you have to take into consideration that the manufacturer is merely trying to sell their product. i am not going to say they are lying but you can surely manipulate the data for better results.

to me, the dyno is just a good way to document how well your car is responding to the mods you add...not a mine to yours comparison. if you have a baseline before you start and then use the same dyno under the same conditions this is going to be the most accurate.

i would like to see a dyno shoot out between the header manufacturers to see who is the best. since this is one of the more expensive mods out there this would help out those who are considering adding headers. also, since these are such a pain to install most dyi folks only want to do this one time. i also recommend coating the headers too to keep down the heat....the jet hot really works well for this application. i can barely feel any heat coming off my headers....try doing that on exposed headers and you will see what i mean.

good luck to those deciding on the headers....looks like there is a lot to choose from so that is a plus.

 

a Few differences, DC ones are US made and internally the collector is designed different, the DC ones are cleaner internally. Alphawerks and Nexus are manufactured in China same as Top Speed.

here are some pics of the DC one on the right.

 

gee. that is very very clean. impressive. too bad the numbers arent as impressive...

 

mynismo, first, why does it matter where they are made?

Although, second, for the record, Nexus are made by Alphawerks, just modified when they get here to fit LHD 350Z's...

Third, what are the headers on the left?

 

1) its does matter where its made, why? cause quality of the materials, quality of the craftsmanship, and dont you have pride in what you put on your car? Chinese made parts never have R&D or dyno work, they just slap it together off someone elses jig design.
2)Nexus/Alphawerks from what i see looks like they modify the chinese headers from what i heard.
3)Headers of the left are the Nismo Headers (good materials but, crappy craftmanship. on that particular one).
