Exhaust headers

[Didi]

Can i buy something as that

in England?

I found some in the US (http://www.rdent.com/), but it is to expensive to send to Europe.

THx you for the help.

Mine is similar though the exhausts are not joined at the block end.

Unfortunately I do not know where Vegantune got it from for me.

I know Sue Miller also sells Manifolds. You should also give her a call.

Thx for the answer

Until I joined this forum I was not familiar with the word "headers", which I assume means "manifold". Or is there a difference? Is it originally an American term?

[Didi]

Difference between headers and manifolds:

Manifolds- Stock part. Cast iron, large heavy and usually poor flowing. They (mostly) look bad too.

Headers- Tubular, lighter and better flowing and looking. Usually has some thought into the length and size of each tube for better breathing. Almost always makes more power than manifolds and helps with fuel mileage.

That's the difference, I think ...

Technically, they're all manifolds:
2. (Mech.) A cylindrical pipe fitting, having a number of lateral outlets, for connecting one pipe with several others; as, the exhaust manifold of an automobile engine. [1913 Webster]

The single-piece, faster to make, quieter cast iron OEM part is typically called a manifold, while the bend-n-weld tubular manifold is called a header in the USA. Header is an expansion of the hotrod/ street-term, head pipe... as in tail pipe, H-pipe, Y-pipe... head pipe.

Thanks for your replies. "Headers" does seem to be an Americanism. The Lotus manual uses "manifold" to refer to all types of exhaust systems and I haven't found a British textbook which uses the term "headers" (but someone probably will).

Hi

You will find quotes of 'header tank' which is really confusing for the translation.

'Boot' is another one to confuse the not English and has anyone every put gloves in their glovebox??

Technically, they're both manifolds, but this is the way I use the terms to acknowledge the distinction.

And yes, I think that the term "headers" originated over here.

Just to confuse matters further, in Australia they're called extractors.

Oh and when I bought my 1969 Cortina (deceased estate, bought from owner's widow), there was a pair of driving gloves in the glove box. I keep 'em there. Sort of feels ....right

I am using Tony Thompson Racing large bore equal length manifold, (now ?420) in my Spyder chassised +2S.

It's a very tight fit. I need to assemble the engine, including head, and gearbox on the floor, and install/or remove as a complete unit

[summerinmaine]

Just thought some of you folk in the Outer Darkness might like to see that in Murrica we do use the terms separately.

Sorry that there's no Elan in the picture.
