ok i got the header. what do i do with the o2 sensor?
88 na. no air pump. it will be mostly straight pipe to back of car. then muffler.
later

Should have the bung there for it....

 

there is a hole half way down the header that you have to put it in

 

Depending on which header you got, the Road Race header doesnt have a bung for the 02 sensor so you would have to buy one and weld it on. Im not sure about the streetable header since I dont have that one.

 

Well, my RB street header had a bung at the collector. The O2 sensor threaded into it no problem, but I did have to splice the wire to make it long enough to reach the engine bay. This is the header that collects right before the flange if anyone is curious. :

 

thanks guys
i have the road race header. so where do i get a bung? what size? any certain place to weld it on? is it ok to splice wire to lenghten the distance of the sensor? right now with the stock header it seems a bit stretched tight.
could i run it to the next piece of pipe i attach to the header in stead of ruining the new header?
thanks
robert

 

stock is a manifold, not header

 

Er...



The stock manifold is a header...

The RB header is a manifold...



Theyre interchangeable terms. Hope this clears it up for you...

 

Ehhhhh I dont remember the size but if you have an exhaust shop near you they should have one. I just had Don Marvel weld mine onto one tube up near the front of the header. He said that would work fine and I havent had any problems with it.

 

header , manifold , you know what mean...........
thanks guys
not sure if i'll get it on before the next race, i still need tires and havn't been able to ge it in the paint booth yet because of all the holiday stuff.
so thanks again
robert

 

oops....
I always heard that stock was manifold, and aftermarket was a header, based on how the pipes went, or something like that.

thanks for clearing it up. now I feel stupid.

 

No need to feel stupid

We all make mistakes

 

ya just ask anyone who has ever bought a FORD.

The stock manifold is NOT a header. It is a collector.

An exhaust header is a type of manifold with seperate tubes for each exhaust outlet that are equal length and usually contain some form of exhaust tuning.


The manifold on rotaries is a big cast iron box that the exhaust exits into. Most certainly not the definition of a header.

However, while some cars do come with a "header" from the factory, generally, a factory exhaust manifold is refered to as an "exhaust manifold" while an aftermarket piece is refered to as a "header".

Here's a good site for info on exhaust tuning -- see "tech articles":

BUNG


sorry, i just wanted to type it in big capital letters

 

yeah, thats what I thought. so I guess I was right.

 

Uh...Look it up in the dictionary. Theyre the same thing.

However, in automotive circles, people have adopted the notion that theyre not.

 

I am not sure what the question is, but regarding the Bung for the o2 sensor you can get one at Napa. Take the O2 sensor to Napa and tell them what you are looking for and they will guide you in the right direction..I bought one for my civic and had it welded in ...They are some kind of Oil ------- Somthings...They will know what you are talking about..I might run up to Napa for you tommorow and find out exactly what they are called...I will let you know..

 

Sorry, not to be nitpicky but not all headers have equal length tubing. The better ones do, but not a necessity for being a header...

 

From www.dictionary.com:
Manifold: A pipe or chamber having multiple apertures for making connections.
Header: A pipe that serves as a central connection for two or more smaller pipes.

A Header HAS to be made of pipe. Since the stock Manifold is not, it is a manifold. By dictionary definition, though, you could also call a Header a "Manifold".

However, the dictionary gives somewhat ambiguous definitions for terms, especially when it comes down to a specific subject. Let's face it; a dictionary defines words to meet a variety of definitions, but is vague in specific circumstances. In such a case, we should refer to a more accurate list of terms.

Hoosier Racing is a well-known racing researcher and product manufacturer.
They define "Headers" as Fine-tuned exhaust system routing exhaust from engine. Replaces conventional exhaust manifolds.
The stocvk manifold is hardly fine-tuned, and is replaced by one that is, such as the RB unit. By definition by a well-known racing supplier:

Stock is an Exhaust Manifold.
The RB unit would be a Header.
