Inactive "Active Valve Performance Exhaust"

[RAM]

My 2018 Mustang GT shows in "My Mode that Active Exhaust is not available and when I scroll to Exhaust from the Pony button I am unable to select anything but normal. Sometimes it will let me select another mode but the sound does not change. The dealer is going to order a new exhaust system. Anyone else have this issue? What was the fix?

Yep, see my earlier posts

My Ford dealer replaced the exhaust system under warranty!
