any straight through muffler thats legal would be good... doesnt need to be big but most straight throught ones are around 3 inches. Pitstop are fitting rear mufflers free this month, an RPS muffler is around $300.
As for piping I think your standard pipes are 2 1/4 inch so thats probably fine unless you really feel like going little bigger... you may want to remove the catalytic converter
