Summary
New Caterpillar 6NZ mod using crisp audio. Added turbo and startup effects.
Description
C-15 6NZ sound mod for M923A1. This mod replaces sound of the motor for the M923A1 to a CATERPILLAR C-15 6NZ. New, crisp sound files with turbo, startup, and stop sound effects added. I made this because my previous suddenly got very popular and was just audio from a YouTube video. Thanks for downloading!
