I noticed that the car has no spool or blow off sound even when the race turbos are applied, you can get the sound if you swap the motor but it losses the sweet exhaust sound.
The Hellcats lack the supercharger sound too.
Huracan and audi R8 lack the exhaust pops from fh2/fm6.
Also all the v8 jaguars lack those pops.
Jonk1969(Dev) has said that the Valiant charger will get a sound fix so maybe we can point out other cars too.
