Performance exhaust?
Hello everyone, I know this is a weird question but its something I would really like to know. Last year, I finally saved up enough to buy my dream car (2014 1lt m7). I saw a white one at the dealership and jumped on it. After reading more about my new machine, I discovered that some new c7's come with a performance exhaust option, others do not. When I purchased my c7 I did not pay any mind to whether or not I had the npp or not, and now I simply do not know if I actually have it or not. I certainly hope I do not sound stupid in asking this, as when I first saw my beautiful new vette the only thing that came into my mind was me driving it off the lot, not making sure it had all of the features I wanted. Attached is a picture of my stingray.
Thank you!

Sure looks like it! Another way of knowing is that there is "engine sound management" or something like that under settings in the touchscreen display (center console). There, you can select the loudness of the exhaust

You can tell by the four evenly spaced tips of a diameter that is larger than the standard exhaust and the presence of the valves just forward of the outboard tips.

remove fuse #41 under the hood if you want it loud 100% of the time, I did and love it, just keep the fuse somewhere in the car in case you don't like the drone on long drives.

Why is that any different then just going into engine sound mngt and putting it in track mode all the time?

If the exhaust pipes are flared as in the photo, you have NPP option or Perfromance Exhaust. The non NPP has non-flared exhaust pipes, and are pretty easy to see the difference.
You got them for sure. The sound is simply awesome.

The valves close even with engine sound management turned all the way off. Most notably in 4th at about 1500 rpm. With the fuse pulled the valves are 100% always open.
