CAT 3406B ADDON FOR W900 LONG BY RICH05TV V1.2

- This is the Engine Sound Mod by Zee with added support for the Kenworth w900 long by rich05tv. This mod is on version 1.6b. - Tested and works with 1.38.x - Please let me know if there's anything I need to fix for the ADD-ON and I will try to fix the issue:) - I will update the Add-On Mod when Zee updates his actual mod (for louder turbo noise)   **PLEASE NOTE** THIS IS NOT MY SOUND MOD, THIS SOUND IS BY ZEE. THIS IS ONLY AN ADD-ON FOR THE KENWORTH W900 LONG BY rich05tv.
