If you have any questions regarding this siren mod please let me know in the comments below. I hope you all like this. =)

Update: I reduced the file size to fix any issues regarding muted sirens in game due to file size of the audio vehicles archive over 15.75MB. However the audio quality have not been compromised.

Thanks to TheRealNBK71 (aka awesomeburodude on youtube) for giving me permission to edit and re-upload his GTA 4 D&R Intimidator siren mod.
