I have had my 2016 C7 8A without competition exhaust for just over a week now and I have noted no difference in exhaust note while driving in Touring/Sport/or Track. Should I be able to hear a difference or is it because I do not have the competition exhaust?

Without the NPP exhaust option, no change in exhaust tone.

You have the AFM valves, but not the NPP valves, which controls the tone (loudness) via sound management.

Thank you.

Would the 2015 Z51 have NPP standard, option, or not available?
Thanks

'15 Z51 has the NPP as standard.
