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 now...do 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
Thanks

They should work the same. My 2019 Scat worked like my Hellcat does. Lay underneath it and have someone put it in SPORT, you should hear the loudness easily.

Better yet, when I left my garage yesterday, the door was open. When I started it up, it was a lot louder until they opened (yes, it's open when quiet and closed when loud) and ran through the resonators. In 10-12 seconds, a lot quieter.
