Honestly i'm not sure. The only difference I am aware of though is a different 02 sensor that was used in the early years. Turbo is the same, not sure if the single exit exhaust played a role in the downpipe style or not for the early years.
All parts removed from a 2011 Gen 2 Mazdaspeed 3. All parts have around 6k miles on them.
