I was told the a header from any B series will fit another B series. Is this true?

Like a B18C1 header fitting on a B18B.

 

a B series header should fit other B series from what i've read. do a search. there are plenty of posts that are similar to your question.

 

yes as long as its 90-93 and 94-01 because my friend got the 90-93 header and it didn't work on his 98 gsr motor... just my thought

 

the flange on the head is the same but the lengths are different on some cars. like if u put a GSR in an EG then u need a b16 header for it to fit.

 

well the GSR header is longer than a B16, so you might want to be careful with a lowered car. b16 would be a better choice (in the case of a height problem).

 

Thanks for the info guys.

What about the O2 sensor? Need some type of special tool to remove it?

 

nope, just a wrench and some muscles

 

i used a gsr dc sports ceramic header on my b16 eg.

the header does hang low, but it's not to bad.

The header will NOT reach the stock cat, and the flange is "backwards"

you need a GSR type (all integra?) cat, hi flow cat, or test pipe to bolt up to standard civic exhaust (like stock or my RS*R)

good luck!
