I would guess less MPG because it sounds so good.

I have one on my 2014. Can't say I noticed any change in mileage. There are just too many external variables to conclusively if it did anything other than make it sound so much better. Personally I would take any claims to changing of better/worse MPG because of changing of the exhaust or air intake with a grain of salt. Gas mileage varies enough on it's own without any changes to make such claims of better economy.

 

For example, I just did a round trip this week into Alberta and back roughly 500 miles each way and saw a difference of 4 MPG despite travelling the exact same route, cruise set to 65 MPH and no wind to speak of either way (calculated manually, not with the DIC).

 

The only way that I can explain the difference is that on the way there the hills were generally more steep on the east side of them then the west.
