i'm still stock, and i'd like to upgrade to an aftermarket y-pipe. What is the best one that provides optimal performance, nice sound (though not too loud under acceleration, and suttle during highway cruising), and still get good mileage?

 

All Y-pipes are basically the same. That being said, pick up a Warpspeed or Budget as they won't break the bank.
