Default pre-cats??

Hello everyone. I'm new here and I just bought a 96 gt. The car's only mods that I knew of were a flowmaster cat-back and k&n CAI. However, I noticed that my car seemed a little bit louder than most stangs with cat-backs. When I looked under my car to check the mid-pipe I saw that it was a stock mid-pipe however the last 2 cats on each side had been deleted and replaced with piping. I'm also confused as to why the car has not brought up a code for this. The only code so far has been for the evaporation system whcih still needs to be fixed. I know the stock h-pipe comes with 6 cats on it all together. However I was told that the first two smaller ones on each side are actually called pre-cats and are more of a resonator. I was just wondering because although the previous owner cut out the 4 rear cats he left the front two small pre-cats. are these pre-cats actual converters or just resonators? I live in NJ which has strict emission laws so if my car has no real converters ill need to purchase some for inspection. Thanks in advance for any help given.

i could be totally wrong but i think the only resonator is the middle one the first and last ones are cats. i'm not positive though.
you might want to take it to an exhaust shop and get it checked out
