i just swaped the b16a2 into my 92-95 hatch. the new engine didnt come with the downpipe (between the manifold and cat). i went to the store to order one and they said they have absolutely nothing in downpipes for a 99-00 Si engine. so now im wondering if any other b series downpipe would work. cuz i know many things on the b series engines are interchangable. thanks.
