From what I hear, the cougar and contour may have the same setup (after all both are built on the same platforms), but if it's made like other headers, it's not going to bolt up to a zx2, focus, AND cougar without modification as each car varies slightly in positioning of various things,, a/c compressor (who needs that though), oil pan, cooling fans, sub frame,etc. MAYBE it would work, but I doubt it,,, basically a new downpipe has to be made. For pre98 contours a EGR hole would be needed if it doesn't have it. And if you keep a/c possibly placing o2 sensor hole in different spot (I didn't look to see where that one was, but hector had to do this, cuz he likes air conditioning).
