Got a header that came off a RHD CRX that a guy put a swap into and i got it left over from the old parts. Not sure which company the header is from but it does have some markings on it and it has the Jasma tag with B16A stamped in it. Header has cutout built into it and the lower section is heat wrapped. Outlet is 2.25", not really sure what to ask for it, make some offers, will ship where ever.
