A free flow muffler can improve mileage but by not by much. It would take a long time to recoup the cost of a new muffler.

Doing it yourself? Just the muffler? $50+/- Take it to a muffler shop where they'll replace the exhaust pipe, the tail pipe and the muffler with a "lifetime replacement", and it could get expensive.
Normally it will only take a day for two...
not for sure but with some scooters they restrict them with the muffler you may be able to take the muffler off drill out the inlet side of the muffler to allow more air flow
