er um, I dunno what kinda factory manifold u have...
but S13's are VASTLY different then the aftermarket style.. pretty much all DOHC aftermarket headers look the same to me sans the S14 Greddy, and I've only seen one of those.....
DOHC headers are 4-2-1 design, while the factory uses a 4-1-2-1 type setup, all the runners run into a log style cast manifold, then it has two outputs that run down by the transmission that y into one pipe that goes into the Catyltyic converter.....
take off your heat shield then look at a pic of aftermarket headers... vastly different
