Yes, but for some reason every car responds differently to the same mod.
For example, most Z's and G's don't lose power @2K RPM with the XYZ pipe, but as you saw in the example you referenced sometimes it can. And I can't know why without being able to personally test the same car with the same set of modifications and start switching things around to figure it out.
Variations of dyno results can be seen in every class of breather mods and engine models. Its fairly normal. One thing I have seen is exhaust mods interact strongly with eachother. Both on the dyno results but even more so on the sound.
