I'm wondering what types/brands of header people have run on their 88-91 hatch or crx with a b18. I have a b18a1 and i don't know what will fit. I've heard one piece won't fit, but not sure.

 

what are you trying to apply, a 4-2-1 or a 4-1?

 

was thinking 4-2-1 two piece since it would probably fit easier. But i would like to know what can fit in case i come across a deal on a 4-2-1 one piece or a 4-1 one piece.

 

I think you should be able to get a 1 piece in there. The only problem is you gotta install it from the bottom up and it will probably be a huge pain in the ass.

 

thanks, that's what i thought. does the header have to be for a 90-93 or will a 94up header work also? Isn't the main difference just the placement of the bung for the o2 sensor?

 

yea man i still have the two piece 4-2-1 header that is alot better to install if you are interested

 

ya, i think i'm just gonna buy a new DC 4-2-1 two piece header. Thanks though. Do you know which one i should get? there's one for a 90-91, 92-93, and 94up. What are the differences between these, will any of them work? I heard that the 90-91 has smaller piping. I'm not worried about the placement of the o2 sensor.
