CAT 3406E & C15 ENGINE SOUND MOD REWORKED for ETS2
First part of the video is with the new Cat 3406E, then the second part is with the reworked Cat C15. This mods adds 2 engines for the 379 & T800 in the shop.
The difference between the 3406 & the C15 is the 1500rpm sound file, the air gear, and the jake brake.
