I know that the muffler system on the 5th gen is one of the changes Nissan did to vary when the valves open for cruising or WOT. I believe the design of the stock air boxes are different as well.
The difference though in the 4th & 5th gen is almost a moot point because the 4th gens are lighter so the difference in the hp was done to make up for all the extra weight the 5th gen Max gained.
The 4th gens due to their lighter weight have better 0-60 times and the 5thgen usually catches up with the 4thgen before the 1/4 and pass them due to the way the vvt shift adjustments in the engine and the valves on the muffler opening for WOT at the higher end< this is the reason 4th genners opt for the MEVI to be able to continue pulling higher in the rev range and on the top end of especially 3rd gear.
I'm not certain as to what other changes were made but I know that the muffler is one of the major ones.
