Although the Vitesse (and Twin Plenum) both use the 4CU system, the 
computers are internally different.  Vitesse and Twin Plenum were never 
fitted with cats.
The RR plenum for '87-'95 Classics is the same casting as the Vitesse.  
If you have smog inspection, the RR plenum would not technically pass a 
"visual inspection."  If you are looking for something that will just 
pass a sniffer test, you are better off using the RR 14CUX system and 
three way cats...power potential is easily 240HP for a 3.9.  14CUX is 
much more tolerant of cam changes.  If you want a 14CUX system or just 
the plenum, I can supply either.

Haven't we had this discussion before?
