    Hi

    I got a 97 civic EX (si for canadian model)

    With the d16 sohc vtec (127hp) and I want to swap a B16a2

    I was wondering if the manifold+headers of the b16 will fit straight in my exhaust? (In the catalyst)


    Thanks!

    IIRC, D parts are not interchangeable on a B series motor.

    he's asking if the b16 header will bolt up to his exhaust..

    it all depends.. it may be too short or too long.. thats when you take it to a muffler shop and spend $40 to have them fix it.. but if they're equal length then it should bolt up

    Allright!

    I was more talking about the diameter of the piping .....

    If it was equal or not.. I think the lenght is the same because the b16a was OEM built in thoses civic, (civic SIR) so it should be the same lenght with the civic ex!

    Thanks guys

    they are both 2 1/4", but the diameter is not the problem. the 2 bolt flange that attaches the header to the cat are off center. you have to either cut and reweld the flange on at the correct angle, or get an omni/blox adjustable test pipe. i read somewhere recently that the 90-91 teg cats have floating flanges that allow you to turn them whichever way you need them, but i haven't been able to verify this personally.

    in the rush to let you know .... and yes they gona bolt up like butter .... at least that s how it owrked for me and i had a jdm b16A2 motor with the 00 wiring harness and my boy repined it , to work but my motor was a japanase b16 from ja--paaaaaaaanaa durrrrrrr but the exausta does work out well i went 2.5 inches from cat back and as far as the cat goes i li ve in florida now and there is now laws regarding the exaust
    but when i lived i pa and i honestly had the same set up as i do now and what i did was took out my o2 sensor .. smoked a dubie

    and put a condoem on the o2 sensor( im a bad speller)
    which was a commonly sold item at auto zone which is a metal condom
    literaly its a metal condom
    and it will settle your electrical issues .. .
    ps ...... niggers

    aaaaaaarrrrrgggggg nigggggggggggggeeeeeeeeerrrrrrr

    Exactly. I actually had to have my cat flange cut and welded to fit on my WSII catback.

    the b16 header flange appears to be angled differently than b18 ls headers cause mine doesn't sit like that, and i assumed all b-series header flange angles would be the same... regardless, it appears that the bolt holes are off by enough to prevent you from bolting it up properly. you can see in this pic how i ghetto rigged my old stock header to my old exhaust due to the holes not lining up. i have a new header and new catback now, with a blox test pipe.
