Hello, I just bought the AWE exhaust on my 2024 Raptor R, and on Quiet and Normal mode, around 1500 to 2000 RPM, there is a intial rattle/hissing sound, then goes away. But on Sport and Baja, everthing is fine. I adjusted it twice and can't get that rattle/hissing/clunking sound to go away. Anyone expereinece the same thing? Evertime I turn off the truck and turn it back on, it defaults to Normal mode. Thanks!
