Does anyone with a 90-93 accord have an aftermarket header installed? i have talked to a few people and they seem to think that our stock ones are just as good as the aftermarket ones. If anyone has any and noticed either an improvement or a downside to the header please let me know.

 

Congratulations. You are one of the few people that know it's a "header" and not "headers." Gains depend on your model. The EX already has a decent 4-2-1 design and gains are negligible. The LX/DX have a crappy manifold and gains are more significant. Either way, a header doesn't do too terribly much besides look good.

 

I dont have a Fourth Gen Accord but My friend has 93 EX and he said when he install his Kamikaze Header He can feel the HP gain so its pretty good HP gain if you can feel it.

 

the exit of the lx/dx manifold is 1.4"

you better be able to feel something changing that out...I need a header BAD

 

i should mention that it is an ex model with the f22 and a cai.

 

As far as I know a factor tuned headder is the best you can get, and that is what is on the 4gen EX and is one of the better things about it than the LX/DX. So if there were a gain you would more than likely see more of it on the LX/DX than the EX.

P.S. You may know this but some people have leaks when installing a new headder one one way around this is to warm the engine let it cool and check the mounting bolts and retorque them.

Well if it's a '92 or '93 EX, it's going to have an F22A6 with 140 HP. If it's a '90 or '91 EX it's gonna have an F22A2 or something with 130 HP. The '90-'93 DX and LX have the F22A1 with 125 HP.

F22A4 I think.

As for the DC Sports header on my car, my *** dyno says .

The amount of power a header will yield is also dependent on other mods that you have. If your like me, and have an intake, and a header, while keeping stock cat and cat-back, after the header, there is a bottle-neck. After getting a highflow cat and cat-back, I expect to see gains that are higher than those expected from just a high flow cat and catback.

 

A lot of people claim they can "feel" octance booster. Most peoples butt dynos are way off, and their mind tricks them into feeling things. Most bolt-ons you will not feel anything with. Unless of course you have a very sensitive ***.

 

Your right to an extent. But before, I could not spin my wheels, I could with the header on. I know a header doesnt do much for low end, but I think that is absolute proof that it does do something.

 

I had an intake ,header and an aftermarket muffler (I was told the factory midpipe was very good to begin with). It made a nice difference in sound and high end power.I reccomend it
BTW mine was a '90 EX.
