What are good muffler tips for a 2000 Mitsubishi Eclipse GT?

I have a Mitsubishi Eclipse GT, and I want to make my car sound deeper and louder by getting a muffler tip, but I don't know much about muffler tips. So I'm wondering what muffler tip can do the job. I'm looking for one under the $70 range. I gladly appreciate it if you'd could give me some links and advise :)
