The cat-back will sound better, a little deeper, a little louder and no drone. I had just the axle-back at first and then installed the mid-pipe and x-pipes (60610) and it made it sound better. Honestly, if you had to sacrifice the NPP you'd be okay, it's not super loud or annoying on the highway or in traffic because it gets progressively louder with higher rpms. I kept the NPP just because it had it from the start but that was just my preference.
