I can tell you that my car is a 99 Z16A GTO and was completely stock when i got it, it had the 2 pre-cats which i threw in the bin when i changed the exhaust system.
However emissions laws got tougher in the later years so maybe that's the reason my 99 had it, in which you may not see on a 91, just a guess tho.
What are you trying to find out with the pre-cats anyway?
