^ Well kinda..
The highmount DP Termi full exhaust (p/n 96480031A), which comes with all the exhaust piping, airbox top cover and Up-Map key. When your bike is reflashed it shows "Hyperstrada Racing" upon key on. I'd probably consider that one producing the most power.
Then you've got the highmount DP Termi slip (p/n 96480041A), which come with the silencer and a Up-Map key. According to Ducati the Up-map provides a even smoother and fuller power delivery. That map should show "Hyperstrada Performance" upon key on on the dash.
Then last but not least you've got the lowmount DP Termi slip (p/n 96480051B), which comes with the Silencer... And that's it. No Up-Map required, so upon key on you'll see "Hyperstrada" or exactly what you'd see stock.
I'd say the stages would sorta follow something like this for Ducati Termignoni;
STAGE 0 (stockish):
-factory pipe, or
-low mount Termi slip
STAGE 1:
-high mount Termi slip
STAGE 2:
-Termi full exhaust (due to airbox mods)
