what muffler for a 5.3?

I want to put on a good sounding muffler that would help increase performance. I want a single inlet and a dual outlet. I have a 99 Silverado with the 5.3 engine. I want it to be somewhat loud outside, (I'm 20 I like noise), What brand should I go with, people have told me to go with the Flowmaster 40 series Delta Flow. And someone else suggested going with Jardine. The only problem with that is Jardine is about $35-$40 higher than the flowmaster. Is it worth it? I'm in college so $35 is quite a bit of money to me!
any suggestions would be appreciated.

Go with a flowmaster series 40. If you can wait for a little time, go dual flow. 40... It is worth the wait.
