I dont care if you all think im stupid...

 

headers are mounted on top of cylinders, they let the gas (not the liquid) go out into the exhaust system and out of the muffler

 

so its the exhaust valves? or is there no such thing? just intake valves? i dunno man....

 

headers (exhaust manifolds), its serves the same purpose as the intake manifold except it is for the exhaust. our V6's have 2 exhaust manifolds, they take the exhaust gases from each of the cylinders and combine them into one pipe. here is a basic example of a header, its for a V8 but its the same principle http://www.jegs.com/cgi-bin/ncommerc...59&prmenbr=361

 

and yes we do have exhaust valves, they open after the cylinder has fired to release the exhaust gases into the header

 

I cant believe you posted something so blatantly incorrect.

If you dont know the answer, dont post BS.

 

ok, starting to make sence... so headers are another name for the manifolds? (exhaust and intake)

 

and the aftermarket ones for our cars havent shown any improvement right?

 

Yes, header is another name for the exhaust manifold. In the common automotive usage, header is only used to describe a tubular steel manifold. As opposed the the cast iron OEM-type manifold.

 

so whats the alias for Intake manifold? footer? hehe j/k. do you know how "header" was derived?

 

They need to delete all of your posts. What a waste.

 

for those of u who think my posts are a waste, KMA !!! look at the time i posted. it was posted at 1 am fools. yea they dont go on top of CYLINDERS. EXCUSE me for being tired and trying to help someone out

 

providing incorrect info at anytime of day or night is wrong. you wouldnt care about the time if someone gave you a wrong advice and your engine went BOOM, would ya?
ignorance has no excuses.

 

there is a difference between wrong advice and wrong information. anyhow, the info i gave was 85% correct.

 

...incorrect. They have shown improvement. Nobody has official #s but people have seen about ~5hp over just a ypipe. That ~5hp could be off +/-2hp...so your guess is as good as mine.

Just depends on if you are trying to extrude every possible amount of hp out of your VQ if it is a worthy mod or not.

 

85% correct? it's like being "almost pregnant" - u either is or isn't.
i'm not picking on you, but admit when u wrong.
