Whelen CenCom siren I converted from my CenCom siren on GTA IV. Option 1 is the original files while Option 2 has the Police Bike's wail as the primary siren for those that wish to use that instead.

Made an update which you can download in 1.0.1 - Changed pitch of wail slightly so the siren sounds more raw.
