Guys ive searched all over for the answer to this question and couldnt find it. I have an integra with a 92-95 b16 sir-ii swap in it. I am trying to order a header (dc sports) for it. When i am purchasing can i order it for a 99-2000 si or no? is the 99-2000 si the same exact engine as the 92-95 sir-ii? any info would be greatly appreciated.

 

99-00 SI, Del Sol VTEC (i think, the one with B16)

 

Yes, you can order a header from a 99-00 Si. I'm unsure if it will directly bolt to the cat flange. It will bolt to the head.
