yes, 95-96 have a hollow pipe, and a cat down low (below the car). For 97-98 this was changed to have the cat in the pipe, and then a hollow piece down below. This makes the two basically the opposite of each other, and makes 97-98 USDM cars different than all other cars
If you live in states that aren't stupid strict on emissions like CA (of if you live in select parts of CA) you could revise your 97-98 in order to match the earlier style of setup where you have a cat below the car and a hollow downpipe type setup.
Here in CA you're supposed to deal with the insane over priced nature of the cat/downpipe and it's use for only 2 years, on only like 7000 cars produced for the US
