okay my friend has a '94 accord.......he of course wants to make it fast....well everyone he knows is telling him to go for headers........he asked me what it would do for him.......i told him i wasnt exactly sure that it would have much of an impact on hp........so someone tell me so i can tell him......am i right or wrong? thanks

 

You should search under header....

 

the header is the exhaust manifold, and unless you are going with an intake and exhaust its pointless (all of which are components to allow more air to enter the combustion chambers, and escape, etc...). you are only looking at a max of 10hp if you're lucky. if he wants maD POWa then he needs to turbo or drop in an h22.

search

 

headers make a huge difference on bigger engines.........

Greddy makes a good one for the 5th gen, and the DC one is ok

 

yep that pretty much covers it

Yeah, like that will ever happen

 

out of all the bolt-ons, headers and exhaust are the most beneficial. Take that with a grain of salt though as thats not saying they will throw you back in your seat.

To get the most out of any engine, the things you need to do are cams, headwork, boost, and tuning.

as a matter of fact i did search before.......so

 

pwned

a good header w/ 2.5" collector and cat back will yeiled 10+ throughout the powerband

 

Yeah. buy mine!

Header alone will do little for you. Get a complete system. And get it stainless. It will complement every power mod you do afterward.

 

If you are opening up the exhaust, would it be beneficial to open the intake, such as a AEM CAI?

 

An increase in air flow is always a good thing. Overall, a better flowing intake is important, like a CAI. Bolt-ons in general are not bad, just not where you will see the most bang for your buck improvements.

 

how would the complete system of cai and headers affect the gas mileage??? will it have an overall liner increase or decline?

 

It is HEADER, not HEADERS unless you have a v6 or dual exhaust manifolds, which will not happen on a inline 4.

I know its a common mistake but its annoying .

CAI and a header usually will not produce a lot of power typically 5-10whp/tq and typically will let the system run easier and will usually yield better performance and run more efficiently.

 

in theory, gas milege will improve....but in the rear world, your gonna end up gunning it alot more.....so in the end, youll problaby get really shitty gas milege untill you get used to it, and overcome the urges

 

dc header is **** any gains would be incredible, not to mention they look like **** after a while. greddy is ok, custom is the way to go, I wanted smsp to make one for my f23 but he has to many projects right now, he wouldnt do it for no amount of money.
