I think Bill is making that claim because the downpipes he sells are 2 seperate pieces..
So you could basically twist one side or the other to get it to fit right..
The driver side downtube on the 89-93 SC, and the 91-93 5.0L MN12 both have a 90 degree bend where they mount to the collector flange..
The passenger side downtube looks pretty close as well..
I've heard a few guys say the factory SC exhaust system will bolt up to the 91-93 5.0L MN12s..

I'll just clarify what ClintD said..
The stock 89-93 SC exhaust does not have a bung on the passenger side downtube for the O2
sensor, but will otherwise bolt up fine..
IIRC Joker77_2005 was
using the SCP Catless Downtubes on his 5.0, and said they fit perfect..
I hope that helps..
