Most Power From A Header

[tegstar83]

I was reading this site http://www.modacar.com/products/Acura/Integra/MODAHEA/
and it says that the Dc sports header is the header that makes the most power available on the market. Here's a qutoe : DC Header 4-1 is a Stainless Steel header and is all about making power.
DC Sports Header 4-1 Stainless Steel is designed for utilizing all the information from DC Sport's Dyno Testing.
DC Header 4-1 Stainless Steel makes the MOST POWER of any 4-1 header on the market.
DC Sports Header 4-1 Stainless Steel pulls strong from 4000 RPM all the way to redline without losing any power down low.
DC Header 4-1 Stainless Steel use the new lightweight flanges on both the head flange and the collector flange along with the mandrel bent tubing.
DC Sports Header 4 -1 Stainless Steel is CARB Exempt. Well is this true??

Interesting site - also , remember that independant tests might be sponsored by the said brand / item - so there might be alittle bit of bias in the testing :)

I know of a few types of header design that will make alot mroe power than that DC sports ever will - but the price is heading to $1k + .

Also , CARB compliant AFAIK , is not relevant to our country at all ( is only the US i believe ?!)

Have a look at this (Dyno plots available):

yep, their emission laws are tougher than ours too.

I know it's all about design but can someone tell me how the 4-2-1 headers make the same power as a 4-1 header? Also the companys that make the 4-2-1 headers, how do their 4-1 headers compare?

Last Q, so which header is the cheapest?

[joyride]

4-2-1 = power through mid section of rpm band
4-1 = power at end of rpm band

thats all i can tell u lol

Haha that sounds like a direct copy + paste form the DC sports website :p

I think the power is off on these figures JDM Type R's have 195 hp.

What types of header are they??? how much more power???? really a lot more??? i would like to know.....

[type one]

headers are headers... any reputable header wit a 2.5" collector is going to do the same thing... toda v spoon v JDM 4-1 who the f8ck is going to feel the difference.. i challenge you all.

thats wat i think... i totally agree with u...... wanna know wat header that creates a lot more power than other headers if they even exist....

its ging to have to be a custom made header with some serious "curves" hehehe... depending on your mobile, the curves might mean a loss of a/c and p/s.
