Hey guys im looking to buy some headers from someone that just contacted me but i have a question. I need them to fit a b16a which is on my 00 si and he says they came off of a b18b1. My question is would they fit? Also will the downpipes bolt straight up to my stock piping and what do i do about the o2 sensor thats not coming with the headers. Thanks guys

 

they will fit, but the down side is they will hang down maybe half an inch lower, because they are made for a taller block. other than that they will work fine.

 

Awesome thanks . He's selling me megans are those any good? I have in my head dc are the best and thats what i really want but i have learned to settle with what i get lol
