Best bet is a catback most likely. I know some people have been happy with resonator deletes as well.

My car had the first resonator deleted when I got it, then I had the rear mufflers cut out and put 4" diameter, 18" long Magnaflow stainless tips installed. It was loud and sounded great! I got compliments all the time.

I just went to S2K AP2 tips which use 2-1/4" pipe all the way out and it's WAY quieter. The big Magnaflow tips made a big volume difference, apparently.

I started with just tanabe medallion axleback, then put PPE headers, and the car got quite a bit louder from the headers.

I did SRT intake/ecu a couple days later and that added a lot of induction noise, but really nothing to the idle sounds , or the sound at low throttle when just driving around town
