If you have a really sensitive car, any aftermarket may not do. Aftermarket cats have very little active material in them compared to an OEM. Certain vehicles, especially newer Chryslers and Asian vehicles really throw a fit.
Your old 92 Toyota has absolutely nothing checking catalyst efficiency, so this is not an issue. Your truck could probably pass with no cat at all, so any aftermarket cat should do fine.
