muffler for an 05??

Hey, so this is my deal. i got a 2005 sxt sedan. Its the 2.4L V6, and i want to get a new muffler on it. I'm a student with a part time job, so i'm not exactly loaded with cash.
I want to get something with a deeper sound to it, and not too aggressive in regular driving conditions. But, i do like to drive rather, enthusiastically., at times so something mid to upper-mid range in volume would be nice.
Any ideas as to what i should look into purchasing?

if it isn't broke... don't replace it unless you need to

you want a deeper sound? drill some holes to your existing muffler
