Simple question, will all B series headers interswap pretty much?. Reason why basically is cause if i look up b18 header, either 4-2-1 or 4-1 for integra, ill always get 94 and up integs or gsr, or type R. It's like D series headers right? they all interswap with each other regardless of what year you get, it will still fit!. Little help please.

 

so an ITR header will fit an LS motor right

 

I think it will.

An ITR header will bolt right up to an LS. The flange and the overall length are identical.

 

I think thats what i have on mine, cause i seen what it looks like in another thread, and it looks like mine pretty much, cause my header doesn't look stock really, plus the heat shield is missing so yeah it's been worked on before.

 

Does the ITR header really bolt up to all B-18s?

I know the ITR uses a B16 head...

... maybe I am thinking the intake manifold is different... i dont know.. let me know how it goes, good luck

 

Your thinking intake manifold. The header should bolt up at the head

 

Cool, thanks man, i didnt realize that..... i thought ive been in the game a while, but you can always teach an old dog new tricks !
