Whelen Howler Siren

This is a Whelen Howler siren sound mod to replace the Ambulance sirens in the game. I quite enjoy the Whelen Howler as it's basically a Whelen Cencom with a rumbler effect and it sounds awesome! It fits quite well with certain fire trucks and even some ambulances (and paramedics SUVs). =3
