i should probably clarify......stick shifts sound awesome with straight pipes, as in , no mufflers. autos sound dumb.
i would also recommend x pipe, but definitely not mufflers. it won't be too obnoxious if you're not on it, but make sure you run the pipes all the way back, otherwise it will sound like a clunker - you lose sound quality with shorter pipe, especially these guys dumping at the rear axle.
it will sound melodious once you put your foot into it, just don't be silly in town with it.
