I personally dislike flowmaster. I've dealt with their noise for far too long and finally went with magnaflow. Not only did it sound more peaceful at idle and light cruising, it added a lot more power compared to flowmaster. It's not close to stock quietness, once you get about 2500 rpm, it starts to growl nicely.
I would stick with all magnaflow or greater/equivelant.
