Generally speaking, mufflers don't improve gas mileage. They reduce noise by disturbing or smoothing exhaust flow.
That said, an excessively restrictive muffler can increase exhaust backpressure causing the engine to labour and decrease efficiency. In this case, replacing the muffler with a less restrictive unit can improve gas mileage, but the same can be achieved by eliminating the muffler entirely.
In some (uncommon) cases it is possible for a muffler that flows too freely or is missing to cause the engine controller to operate in a less than optimal mode. In this case, an original type muffler can help by restoring the state of tune. The same effect can be achieved using a baffle or simply denting the exhaust pipe appropriately.
