Code 3 RLS Siren Mod (Hi-Low Version Included!) 4.0

Also recommended with SirenMastery as well.

Update (11/10/2016):
All tones have been re-sampled and are now better quality and loudness.

Update (08/15/2016):
Resampled the yelp once again and included a hi-low tone in a separate .rar file.

Update (08/10/2016):

I did some minor fixes and resampled the wail from a new video.

Update (07/19/2016):

I've sampled the siren from a new video and have done some edits. This is a complete re-work on the siren sound mod. A Hi-Low version will be coming out soon this year.

*Important Note: In order for the sirens to work successfully without the vehicles.awc to exceed over 15.75MB, please extract the fix included in the .rar folder to the folder where you are extracting to for this siren mod. This fix is made by GravelRoadCop on lcpdfr.com.*

*Also Important: For those with the Rockstar version or non-steam version of GTA 5, you must create a mod folder to avoid having the game to auto-update and remove any mods or changes made to the game's data via OpenIV. For more information on how to create a mod folder successfully, visit openiv.com (http://openiv.com/?p=1132)*

7 - Extract the vehicles folder (containing the four audio files of the siren) from the .rar file to the same folder that was exported in.
8 – Afterwards, go to edit mode in OpenIV. There will be a warning upon editing mode so be careful.
