What happens after the cat isn't an emissions issue (but it is a safety and noise issue).
Theoretically, you could remove the cat-back from a dual-cat car and run dual exhaust after that.
But, your car would have to be one on which the dual-cat was an option (or you convert the whole thing to be like a dual-cat-optioned car - AKA '89-'92 TPI).
