I got this B16 and it came with an unknown stock header. Now how can i tell what this header came out off? because I am trying to get a cat converter and I think im suposed to know what is my header from... so that the cat will bolt up.Am i thinking in the right direction?

By the way, I compared my header with my brother's b18a header and mine is shorter than is.. if that helps any. Somone HELP!

 

then you have a gsr header, b18 ls, and type r, and del sol b16, and 99 si, are the same size only the gsr is shorter

 

the flange at the collecter on the b16 header is turned in a different position then the b18 header.

 

So I should look for a cat converter for an integra, am i right?

Would a gsr stock header fit on like a b16?

Wrong , i have a dc header for a b18 and for a 99si and the flange is turned the same way

 

^^^ Still need to know what cat...

 

just run straight down pipe

 

&lt;&lt; Need cat.

 

hmm i have a gsr header and it doesn't clear my oil pan on my b16a so it may not be that one (the header i have is a 00 gsr) you might need custom exhaust work done no matter what though.... then you could use an old catalytic converter from the d series engine... thats what I have when I need to run my cat, the rest of the time i use a straight pipe, ebay special!
