I would suggest buying the muffler of your choice and finding a shop to bend the piping for you. I got a whole cat-back with muffler for under $250. Plus you can have them make it how you want. Resonator, no resonator, 21/4 piping, 2/12 piping, cat, no cat (only some shops will do this) If you don't live in CA then you don't even need the large cat under the car. Mine came with it for some reason, but I had it removed. I had heard that only cars designated for stringent emmissions testing would have the additional cat. Maybe I heard wrong. Anyway, the deakership is always going to rip you off, so anything you can do yourself will save money for other mods!!
