Muffler question

Motor is a 318 with eddy heads and about 9.5:1 compression. Cam is a comp 275DEH which is around .484/.494 lift. I also have Doug's headers. I don't want something that sounds like someone is just growling in your ear where its so loud it hides the choppiness. But I would like it loud and crisp where the lope is nice and distinctive.
