As i see it with ur. dp you get rid of some unwantet backpressure caused by the cats in the dp plus a faster spool up time and less heat in the engine
room. From what Ive read about the s.s. system there is 24hp gain with the full system (ur dp) and only a 10 hp gain with with catback (stock DP)
With stock exhaust you still have cats just not on the DP....we are taking the car with the catless DP thru the SMOG TEST ONLY center to see. Since the DPs are covered by the shorud, and you cant see them from the top it will pass the visual.
