not sure I bought an A4 header.

[drummerwill]

tripped over a tubular header in the section of CB7's and it was in front of an EX so I assumed it was the A4 header and bought it for $50, what i'm curious about is where the O2 plug is located. Is it supposed to be down by the flexpipe? I know where it's at on the regular headers, but is that different because of the tubular style?

Does it look like this?

If you have the o2 in the header, and the one you're buying (anyone) has the o2 in the F/P,
then you run a simple re-wire and you're done .. the old o2 fits as well .. if you wanna keep it.

And yes .. that looks like it alright ..

I was asking if his looked like the on in the pic I posted lol.

LOL! I .. uhh, yeah, I knew that ..

It's close to that, but no big welds like that one has. Here's a pic:



I was assuming it was the A4 header cause it was partially underneath the front of an EX CB7 that was missing the block and surrounded by Accords on all sides.

I'm pretty sure that's the a6 header.

yep that's an ex header, hope you got the down-pipe that went with it because a a1 header is 4-1 and the ex header is a 4-2-1 header. the o2 sensor screws in right in front of the flex pipe on the ex header, where the down-pipe goes 2-1. if all you bought was the header, youll need to go back and get the downpipe to hook the exhaust system correctly

Crap, i forgot to check the taillights for yellow uppers... hahaha... fail. Oh well, they're still better than the A1 headers right? would it be worth putting them on or no?

Yep, got the down pipe too, spot on with what you said, it was all already unbolted sitting in front of/underneath the car begging for me to buy it. The flex pipe is trashed, though, looks like the yard guys cut it to get the cat off.

[Brandoncb7]

The a4 is better than the a6 and a1 and the a6 is better than the a1 so yeah it'll still be better than what you previously have.

[drummerwill]

Sweet, I know the A4 is supposed to be better, but to me a 4-2-1 is miles ahead of a 4-1. haha... now looking at the pic of the A4 it's all tubular, where the A6 is cast? other than that are there any other differences? like the diameters are the same and such?

[Brandoncb7]

I honestly don't know on that one man.

[HATCHing]

wow for $50 you could just buy a cheap ebay header for that price.

[drummerwill]

ehhh... not too keen on ebay stuff (says the guy with a lime green ebay shortram) yea $50 for the headers, but how much for shipping and then how long would they last? I'm really trying to keep to OEM parts as much as possible just to see where that can get the car.
