post a picture and i can tell you
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?

Thanks, I'll post one tonight.
So is this a stock piece or aftermarket?
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)
I have the stock Fed-spec header on my '00. The lower flange does not look like that.
Thats a stock header when I had bought one of my engines and I asked myself the same ?

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

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

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

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.
The top portion is the one you have
99-00
FED spec exhaust mani
01-03
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
^^^ Perfect Info.
