I don't have any of my own, but when I was shopping around I listened to the videos below over and over to get an idea of the sound. Based on the sound, I can tell the cars below just have the rear section + connecting pipes only and no aftermarket X-pipe/cats.
It's a bit difficult to gauge the volume of the exhaust from videos since some are taken in garages. But, it's not overbearingly loud and if you need to keep it "stock-like" quiet you can keep the revs low and go easy on the throttle.
