Others have reported dealers updating software and ending up with a more muted exhaust sound. I have read the posts asking about this but don’t know any more. It must have to do with controlling the exhaust flaps under some conditions and reducing the burbles under other conditions. You can buy a flash tune like BM3 that will let you customize the burbles and flaps to some degree, and BM3 gives the option of using a stock Competition tune if you don’t want anything more aggressive. But the engine warranty could be voided.
