    I just want to now for example if my b16 DOHC dc sports 4-2-1 will work on a friends 91 si I have a 90 si. He has a 4-1 and wants mine and i've been wanting a 4-1.

    Are the piping size the same??

    i have'nt looked at his but he has mine and says it'll work and thier the same size piping. Will they even bolt up?

    What are the differences?

    I didn't think the bolt patterns were the same for SOHC and DOHC heads. Only one way to tell for sure, I guess...

    Also, there may be some clearance/connection issues as well. The B-pipe may not clear the oil pan, and it may not be the correct length to bolt up to the cat.

    d series and b series header flanges are diffrent...

    and yes, i am positive on that
    some guy sent me b series instead of d and it did not bolt up...

    im with recked b series and d series is far from same bolt paterns - ! and the block of a b should be a little taller/longer which might make it where the headers b pipe wouldnt reach like dohc sais!
