Header Identification

[mikelbeck]

I bought an engine that had a header attached to it... It wouldn't fit in my car, the flange on the header is different from the exhaust and I didn't feel like changing it.

I don't know how many different companies make headers for these engines, is there any way it identify the make/manufacturer of the header?

Thats a stock fed-spec header

[mikelbeck]

Thats a stock fed-spec header

A what what?

[Galantman03]

Thats a stock fed-spec header
possibly, but depends on the year, my 03 one didn't look anything like that

A what what?

you have two different types of headers on the g, cali spec, and federal spec. I can't remeber the differents between the two at this moment

[mikelbeck]

So is this a stock piece or aftermarket?

[4g63lover]

thats not the stock header for the 8G. the lower flange is different.

[Smokey92]

Its stock because that is what my stock header looked. the fed spec (header) were only used on some 99-01 galants. I believe 2002 and 2003 galants came with manifolds (Cali Spec)

[4g63lover]

I have the stock Fed-spec header on my '00. The lower flange does not look like that.

[99galantES]

Thats a stock header when I had bought one of my engines and I asked myself the same ?

[mikelbeck]

That's odd... it was on a 2000 engine that I bought, but the one that was on the engine it was replacing looked totally different. I wasn't able to connect it to the exhaust that was in the car so I wound up using the one that was on the old engine.

Is there a big benefit to using this one over the other one?

[duh2150]

yup, 100% stock 8g header fed spec i have 2 of them if anyone wants to buy

[mikelbeck]

What are they worth?

[99galantES]

I think your going to need the down pipe to match the headers if im not mistaken

[duh2150]

worth i donno probably really cheap and youd need the downpipe to fit it, its a 4-2 header with a 2-1 downpipe with a cat on the downpipe welded, and yeah you'd need the downpipe if you have a cali spec car i wouldn't mess with it at all

[Isaurio]

OK let me resolved this issue. It is a OEM exhaust mani, is a FED spec. Here is the different.
99-00 Have the mani without the build in cat "pretcat" FED ONLY ONE CAT
01-03 Have the build in cat "precat". CALI 2 CATS

Here are some pics.

Cali spec

FYI. People running aftermarket headers and have a CALI spec exhaust system they should use the FED spec of the o2 sensors locations. One o2 before the cat and one after the cat. Because if you leave it as it is, both o2 sensor will read the same AFR making your engine run lean. You could leave the one "o2" sensor on the aftermarket headers, but the second o2 you need to move it to behind the main cat so it could read properly. HOPE THIS HELPS

[duh2150]

^^^ Perfect Info.

[99galantES]

Thats weird I have a 99 and I dont have that type of header mine is header pre-cat

[Isaurio]

So yours is a CALI spec. There are some miss and match on the market. Some cars are order for customer needs. Yours most have 2 CAT. Double check that.

[mikelbeck]

Excellent info there, thanks!

[Isaurio]

No pro.

[99galantES]

It does one after the headers and one after the flex pipe

[4g63lover]

Oh wow, I guess I gotta admit to this one. That is the fed-spec header. For some reason I was thinking mine has the same flange as cali-spec.

[Isaurio]

It does one after the headers and one after the flex pipe

Yeah cali spec the pre-cat is build in with the headers, i have that setup since i'm 02. :) but i have aftermarket headers and that replace the pre-cat. I have only a high flow magnaflow main cat. AUCH. So i converted to a FED spec settings

[99galantES]

the first one bolts on on both ends so i can change it whenever i want without any issues

[Isaurio]

ohh. Take a pic.

[99galantES]

I will tomorrow am I the only one with it like that

See how my cat bolts up on top and bottom

[Isaurio]

ummm. Yeah 99 California spec. It was a bad design that is why 02 03 they made it better.

[99galantES]

Thats what I was thinking cuz my car also came with the black galant trunk carpet I be wondering why half my shit is different lol

[Isaurio]

You need headers asap.

[99galantES]

i will be getting some soon when i do my 5spd swap just dont know what to go with

[Isaurio]

You have a few. I have OBX one piece wrap up. I have no issue so far.
