Exhaust Manifold

I was wondering if Ford had the same exhaust manifold and cat for their SOHC and their DOHC. Would a 2000 Ford Focus SE (SOHC) have the same exhaust manifold and cat as a 2002 Ford Focus ZTW (DOHC)?

If you called your Ford dealer and asked for the part numbers for each, you could get a definite answer, but my guess is no, since the have very different heads, and the engines are just different in general...
