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?
Roverly,
