Dual cats did indeed start in 1989, but there were some cars produced without them. Perhaps early cars got the single cat, and the later cars got the duals.
I have a 1989 borchure that shows the dual cat setup. I used to own a 1989 Formula 350 and it had dual cats. And I do recall an early 1989 Formula 350 that DID NOT have dual cats.
Mark.
PS. Check your RPO tag. IF it ain't there, it did not come with it.
