Uh oh, I'd search first, unless of course your flame suit is on, in which case you should be fine.

Drew, I usually let the header vs headers slide on the Subaru end. I mean technically you have 2 heads connected by 2 pieces of pipe, but it is technically 1 pipe. But yes, that is a huge pet peeve of mine, especially on all other 4 cylinder car's I've owned.

OP, you do not NEED a tune, but to maximize the benefit a tune would do wonders. All laid out in Unabomber's Manifesto, which is a all informative sticky located at the top of this section.

Yes, because there's not 2 seperate banks like on the V shaped engines.

And coupes have one door on each side of the car. Do you say that you need to replace the driver side doors? No. Its a single door.

The number of heads you have has nothing to do with header/headers. Don't be an argumentative prick. You're wrong. Admit it.

How many pieces is it made of?

Didn't we just have this discussion yesterday in a different thread? There's a manifold on each side, connected by a crosspipe.

When you replace a cam, you're actually replacing many cams, but one cam shaft.

Why is called a pair of pants/boxers/shorts? It's just one piece of clothing.
You park on the driveway and drive on the parkway.
Drew claims to be a man but has lady-parts.

Let it go, man.

And to the OP, as mentioned, you don't absolutely NEED a tune, but any changes to your airflow (intake to exhaust) will benefit the most from getting a tune.

If you're looking to swap out your header(s) just because... I'd save the money and get a tune along with it. And a downpipe.

Depends on who makes it? Some have slip joints so technically that one is made of 2+ pieces.

Manifold. An exhaust manifold is not a header. It can be loosely refered to as a header, but technically it is not.

When you replace a cam, you're actually replacing many cams, but one cam shaft.

You replace many cam LOBES in one camshaft.

Why is called a pair of pants/boxers/shorts? It's just one piece of clothing.
You park on the driveway and drive on the parkway.
Drew claims to be a man but has lady-parts.

Pants/shorts/boxers, who knows. I have a feeling that those 3 words were all taken from another language and used as english.
Who cares?
Lies.

Let it go, man.

And to the OP, as mentioned, you don't absolutely NEED a tune, but any changes to your airflow (intake to exhaust) will benefit the most from getting a tune.

Edited above^^^

And this is a huge pet peeve of mine. People need to learn.

I am sorry, i did not clarify my intention with posting. I dont care nor am condescending (a prick?) to anyone that mixes up plurality one way or the other. I also dont want to be argumentative, just don't want people to think they should walk on eggshells around motor head(s). I am also sorry i made fun of you, i honestly thought you would consider my lighthearted questions.

my (wife's)honda has a header because it has a head and the honda crowd was real big on this and i guess it makes sense. The flat motor crowd, including porsche i suppose, shouldnt fuss over this. There is good reason to label it plural, so dont get bent out of shape splitting hairs. (ie twin scroll or not)
