Considering no exhaust should be flowoing out your short ram, the MagnaFlow should be hella louder imo. Adding a short ram to a car with exhaust will generally lower the tone of the exhaust, making it sound deeper.
I don't have a street series (that I know of), but it can get to droning on you from time to time. The trick is to find the RPM ranges where it quiets down. Then you adjust your speed/load to stay there when you make longer drives.
