14.5 MPG to 19.8mpg average

[Bryce18]

Well last weekend I installed H&S mini with 5" mbrp strait pipe on my buddys power stroke and he's averaging over 5mpg better then stock! Ever since he bought the truck the best he could get out of the truck was 14.5mpg now he's getting almost 20mpg! These are highway averages.
He has a xlt CC,sb with 2" lift on 35" tires.

Yep thats about what I am seeing. Just got 22.6 during a 400 mile highway trip with 1500lbs of junk in the back. Not too shabby

Went from 14.5 hwy to 20 hwy also. Went from 12ish to around 15 city, more if I'm easy on it.

Same mods

So riddle me this: Stock, looks like around 14 average MPG. Tuned / deleted looks to be around 18 average. Say the life of the truck is 250k miles. While getting 14mpg over the life of the truck, you will use approximately 17,857 gallons of fuel. At 18mpg, you would use 13,888. You would use nearly 4000 gallons less fuel over the life of the truck. I don't see how the having the DPF of and getting 14mpg will put out less pollution than saving 4000 gallons of fuel at 18mpg with the DPF off. Not to mention the pollution that goes into the production of the Urea and the massive DPFs themselves when they are originally produced. I just don't get it.
