Best Exhaust

I'm sure this has probably been asked before sometime but I was just wondering what you all think is the best cat-back exhaust to get on a 96 GT that is under $300?

depends on what you want...Most people here from what I can tell like the MAC line of exhaust products. I personally like the Flowmaster sound more. Just try to find some sounds of what it sounds like, and see which one you like better.
