Will this exhaust decrease the 5.0L gas mileage?

Interestingly, I had just posted this yesterday:

I'm thinking about putting the factory resonator back on to try and get back some of that old feel.

Flowmaster's chambered muffler designs scavenge exhaust gases, which increases exhaust velocity and allows your vehicle to run more efficiently. This frees up available power and can give you an increase of 1-2mpg depending on how you drive the vehicle. However, it is important to use the correct Flowmaster muffler for your application.
This doesn't quite look like one of our Cat-back systems. Haulinbass09, would you be able to check the inlet side of the muffler case for a part number? That way I could tell you what kind of Flowmaster muffler they used when building that exhaust system.
