im thinking of getting a nice header, but my question is ...
which do i get?

i have a 5-zigen exaust and AEM cai
should i get a 4-2-1 or 4-1 header??

i do whant a bit more midrange power but if the power gains are much different
i would consider going for a 4-1
can anyone give me some input please?

 

toda
mugen
spoon

any other input??

 

4-1 JDM Honda header... "best bang for the buck" (in my opinion)
OEM parts seem to fit a little bit better...

JDM DC holds that title.

 

If you're sticking to I/H/E, I think everyone will agree, with the Great Header Test as proof, that you should stick to either the DC JDM or JDM 4-1 header.

so you guys think that a 4-2-1 header is useless??

what do i do for midrange power

 

Top end power = 4-1
middle = 4-2-1
it depends on what you want

 

would i loose midrange power from stock midrange if i went with a 4-1 header??
sorry for the anoying questions guys!!

 

No sir. You will see an improvement over stock with most any aftermarket JDM header, throughout the entire useable rpm range.

Unfortuantely, ap-engineering's site is down, so I cannot post the JDM DC vs. Stock graph from the great header test

sack-who pages those who saved the charts.

 

what is the difference between the aftermarket JDM and a USDM header
is the USDM still a allaround power gain??

 

A USDM has a 2.25" collector while the JDM has a 2.5" collector.

You can buy an aftermarket header in either size or the Honda OEM JDM.

Generally if you plan to mod your car past I/H/E at all a JDM-sized header will do you best.

 

I/H/E ?????

 

Intake
Header
Exhaust

 

thanx for all the help guys!!

 

anybody has a pic of the 2.25 and 2.5 collector??

 

Here's a few of the JDM DC from another thread:

also depends how much you are willing to spend. there are lots of great headers out there, like Toda, Mugen,Spoon , Hytech and SMS but they all cost over 800 .
and there other like dc jdm , and the itr jdm 4-1 that cost below 500 . is just up to you and what you really want most .top end or mid

 

Hytech or SMSP!!!!!
