active exhaust?

so i have an 18 HC Challenger M6 and was under the car the other day and noticed the exhaust valves. on my old Scat Pack i know that when i engaged "sport" the valves opened up and the exhaust got louder. my car always sounds the same the valves work and if so, how?

This is a real question--flame away if you must, but i seriously have never heard a difference

Your owners manual can explain all of this to you or look at all the YouTube videos
