I'm looking to put some headers in my 94 ex but I don't know whether to to put 4-2-1 or 4-1 headers in because from what I understand the performance difference between the two is noteable. Which kind do you guys think are better?

 

get an exaust and a pace setter header. that would be all you need. you prolly dont have the skill to instal a header but thats my guess.

intake, header, and exaust might only yield about 8-14 hp


i would only get the 4-1 header if you have worked on the intake part of the engine...ie throttle body....manifold....the 4-1 is targetted more for high end power....

I have a DC Sports 4-2-1 on my Y8. It helped more on the upper end than anything (4000+).

BTW, you are only buying one header, so please stop using the plural form.

 

Basic Rules of thumb....

4 into 1 equals better high RPM breathing.

4 into 2 into 1 equals better midrange and drivability.

 

i say 4-1 all the way. the powerband is really high but thats where you are when you are racing. who cares about midrange? ....just my opinion. i had a dc 4-2-1 and later got a dc 4-1 and i liked the 4-1 much better. you can really tell its opening up.

 

Skill isn't really a problem and I have all the tools at my disposal, Is there any one company that really stands out in your minds as the best for a header?

 

Mugen, J's Racing, Spoon Sports, GReddy, Toda i think makes em too.. i have GReddy one and it works like a champ!

 

search for "titian motorsports header test" or something along those lines, in the NA forum, those are the best of the best.


most SOHC people really like Bismoto headers

 

get the DC 4-2-1 header

 

For a SOHC VTEC I would recommend DC Sports. Go with the 4-2-1 two-piece Ceramic Coated. It is the "original" DC header, tried and true. Other ones to consider if DC isn't the route you want to go include: GReddy and Apexi. There are more companies out there as well. If you think you may go turbo in the future or are on a tight budget I recommend you find a used one in good shape. You can't go wrong with checking out the classifieds section here. Good Luck.

I never new there was skill involved in bolting on a header.

I like the 4-1, personally. I'm just running the JDM 98-Spec 4-1 ITR header on my '96 ITR motor. It's lighter, feels better, and looks cooler , than the stock 96 ITR header.

A 4-2-1 will give you a little better midrange power but it all depends on where you want to increase your power.
Either way...I think either way you go, a header isn't gonna make your car feel like it's on nitrous or anything.

 

3-1 x 2 booy!

mugen - not for sohc vtec
j's racing - not for sohc vtec
spoon sports - not for sohc vtec
toda - not for sohc vtec

however i have a fujitsubo one, for a sohc vtec, i think the only one in the states.

if ur going to spend time at the track, get 4-1
if your going to want decent power for everyday driving 4-2-1 is for u

personally i wouldnt get greddy or dc for any car i have. apexi makes one for sohc vtec. i'd jump on that (inlinefour.com)

remember, u get what u pay for, dont make a bad investment.

exactly and DC makes **** that makes HP. don't spout out **** when you haven't even seen dyno comparision, for the money DC is a great header

 

i have a b16a2 and prefer 4-1 because of the hi range power increase!
