I bought a civic o7 ex. Just recent i did a project bought exhaust system and AEM cold air intake. I want to buy a header but know if my car as one. Right were the header goes there is a big catalyc. I am woundering if my car will have a header or not?

 

huh?
Didn't you ask this in your last post? And no one could really understand you?

 

Thanks for your help man?

 

If your car will "have a header or not?
Pretty sure every car has a header.
Again, not sure what you're trying to ask.

 

Actually it has an exhaust manifold.

 

Sounds like he is wondering if his car comes with a header,

your car, like every stock vehicle has an exhaust manifold, a header is an upgrade to the stock piece.
your car, therefore doesn't have a header, so go buy one and you will be golden, unless you enjoy your warranty. cuz they could jeopardize your dealer warranty work.

 

An exhaust manifold and an exhaust header are the same thing. A header normally means a performance manifold, but in essence they both do the exact same thing. Just a header does it better then a stock manifold. Do a search for performance exhaust manifold you will get similar results as if you had searched for exhaust header. Headers are generally better because they reduce back pressure in the exhaust system and help the engine breath better.

 

thats basically what i just said, but a little more fleshed out. "Header" (or "headers" for V engines) is a performance upgrade to the stock exhaust manifold.
