Get your DP and UP replaced if you haven't done so already, and get a tune. Don't replace anything from the catback because it'll be loud. From my understanding, simply replacing the DP will increase noise and deepen the growl and unleash some of the rumble.

You will also get a huge performance boost from stock. Best money spent IMHO.
