Any dyno's anywhere?

 

damn, that's cheap

and the design is like the nismo

good power/money ratio

 

Listed for a 350z...

Yet pics shown for a b-series honda???

Talking about a two-piece header design???

... I'd rather point you towards Stillen if you want to save cash.

 

they are 1 piece from what I have heard so far from AEM, not out yet, and wont be out for at least a few months still

 

they show the wrong pic on that site obviously, but from what i've seen it looks like nismo, stillen design

 

here we go

No their not, the Nismo has a much better collector design and on closer examination I say DC Sports isn't equal length, certainly more so than the Borla, but it does not look equal length to me like the Nismo headers. But yes they are cheap to buy, they'll have their day on the dyno.

 

well, the price is definitely right! how can it be that cheap? I remember when i bought one for my Integra, and it was close to $300, and that's just ONE!

 

Hmmm, they have a decent rep...wonder how they'll do with our car.

 

I didnt know my Z was a 4 banger? Hope they do good though.

 

ahhh, you're correct; some reason i kept thinking dc sports was like nismo.

thanks for correcting.

 

how can you possibly tell what has trhe better collector from seeing the outside?

That is the mild steel (ceramic coated) version in the pic

i don't see how they could be 500+ dollars cheaper than other manufacturers and have the same quality

 

Nismo headers arent equal length, are they?

 

Look at them again you can tell the difference, abrupt angle's coming into the merge point and at that point the DC Sports header pipe the is at it's 2.25" diameter, it does not combine at a larger diameter then blend to the 2.25" to reduce turbulance, and enhance flow. The Nismo brings it's pipes to the merge point at a much better angle, less abrupt, and into a wider collection pipe width that blend's slowly to 2.25" furthermore the Nismo has a defuser piece that is mounted in the center of the collector inbetween the point that all three pipes combine, something else that enhances the Nismo headers collector and that the DC Sports will not have. I'll add that the Crawford has a superior collector design as well, though I do not know if the Crawford design has the defuser inside it's collector.

I don't speak on things unless I can back them up. I researched collector design in advance of building my exhaust system (since avaliable X-crossover pipes didn't measure up, I created my own).
I don't sell stuff and I don't have brand loyalties to corrupt what I say either. Frankly, I've owned a Dc Sports header on another car, I actually liked the power gain, but let's see a independent dyno so we can draw a better conclusion beyond my observations on collector design and tubing lengths.

Pic of design superior to above

 

Your right, the crawford design is, Nismo next closest (jezz, are they or aren't they?. I have the Nismo header sitting in my garage, but how can I measure each tubing length and come out correct?

 

Say what you will about these, but at that price, they can afford to be 'not quite as good', lol. Want to see some dyno results on them of course, but borla said that there headers don't add much and yet they are STILL $600. These are even less, hopefully the results are at least decent.

BTW, there is someone who has stated that they are getting like the first set of these on his car, and he is a poster on this site. Hopefully we can hear from him on these headers.

 

It's amazing how even low end headers for the z start at 600 bucks. You can pick up entry level SB Chevy/ Ford headers for 200 all day long. DC has put out some pretty good products for hondas for quite a while. We'll see how their attempt at the z part works out. I think the versatillity of us domestic engines has allowed companies to make a large amt of one product where as most imports although they share the same platform have limitations which do not allow parts compatibility.

 

i dont see the pic. All i see is a sign that says "overboost"?
