Flowmaster exhaust questions

Did a search but really didn't get the info I needed. We are used to haveing a pick-up truck first of all. Our 00 Expy is our first SUV type vehicle. My husband has a friend with an F-150 Super Crew who has the Flowmaster with Dumps (where it is duel exhauls that drops off under the truck and does not exit behind the truck at all) It sounds very good but was reading on here that because of the gas tank location on the Expy, the duel exhaust period might not be possible. We ARE taking it to a professional exhaust installer to do this and will be going later today to get a price and figure out exactly what we are going to do.

Is it true this might help our gas mileage (5.4L 4x4)?

Will it hurt our HP or towing ability?

Anything else anyone wants to add or give opinion on this?

Don't expect much in terms of performance/mileage gains. Do expect more noise.
