Cat back exhaust question

Pulsar arrived,installed.
200 miles driven in econo mode,milage went from 12.8mpg to 15.3mpg imperial gallons. Time will tell but any increase in mileage is what I was after. RB

You might want to drop an email to the Ram engineering team and let them know you figured out a way to improve the MPGs by 20%. After some of the best automotive engineers in the field spent years and untold amounts of money trying to meet MPG guidelines I'm sure they'll be interested to know the answer was as simple as buying something off Amazon.
