And you realize something like 80 or 90% of the emissions are due to cold start and warm up on the EPA cycles, right? The next big chunk is transient and intrusive diagnostics. Steady state emissions, driving down the road, are effectively zero. The cats are converting everything to water and CO2.
You will cut CO2 though, if you are considering that.
Are those numbers for the '13 model? Did it change? Stuff I found was old, but only mentioned the first couple years.

the next update was 2015 which the front end changed 0.34 and smaller mirrors (these mirrors can be modified to fit on mine) but it's pricey at about 350$ for just that the 2019 might be slightly lower as they added air ducts
the biggest drag in the front is the mirrors, because of the size of them.
you can hear the wind dragging on them at about 75 or so
the only reason i'm able to get the good mpg is because i use 91oct as it's able to keep it in V4 mode much longer then 87oct ( it hyper switches from v8v4v8 i'm pretty sure that is bad for the engine i.e wear and tear wise to the AFM system )
