I installed a AIRAID CAI about 2 months ago on my new 2014 Mustang V6 and I noticed a little better throttle response and much better sound from it under the hood. Also noticed a slight bump (higher) MPG not much, but maybe 0.5MPG to 1MPG.
2 days ago, I installed an axle back exhaust (MBRP) and so far I really like the sound of it......but my MPG's have dropped about 1-2MPG. This is according to the digital readout on my dash that shows my fuel economy. Also noticed just a slight LOSS in throttle response......I assume its due to the reduced backpressure of the new axle backs.
I don't know if the computer needs to be reflashed or is this a common issue when freeing up more air......losing backpressure thru the exhaust system.
Anyone out there can share their own experiences with a CAI + Exhaust on a 3.7L V6 ???

FIX: A SCT tuner with custom tunes will help get your power back!!!!
American Muscle, Brenspeed and VMP are all reputable tuning companies.

100% agreed. I found that after I put on my intake and exhaust, I would drive a bit more aggressively so that I could hear the car more, effectively lowering MPG. Of course if you drove exactly the same as you did before, likely you would see a small increase, but nothing major.
