What is the best aftermarket muffler for a Honda Civic?

I have a 2008 Civic LX which im trying to have a little fun with. I know only the basics when it comes to cars but I am looking for a muffler that will make the car sound a little more powerful. I've noticed that a muffler will only give you a limited boost to HP which im guessing is why they are all relatively inexpensive, but what im mainly looking for is one that will sound the best. Iv looked at a few Universal fits from DC Sports and Magnaflow, but many people have suggested Skunk2. My problem is that im not really sure which one would sound the best or how to figure that out, before buying one and having it sound like a cheap piece of ****.
