B18a1 header & down pipe
Let me know what you have for sale. Stock is ok.
I bought a Civic with a swap and the car has the b18a1 manifold and the Civic down pipe, so it DOESN'T have an 02 sensor!
I either need the b18a1 downpipe with the 02 sensor hole or a Civic manifold.

Can't I use the non 4/2/1 and just get a downpipe that fits that?
Is there anything wrong with it? Will it fit a 93 hatch?
