Cat C15 engine sound V2 for the Peterbilt 389


Hi all, here’s a little update of my Cat C15 engine sound.

The zip archives comes with two mods, one is “normal” the other one
has the turbo and gear shifing lowered by 50% from the original.


The external exhaust sound comes from my friend Volidas. Thx to him
for this.

    Can’t get it to work with the 389. Not sure why, put the truck and sound in mods but still have the Cummins sound not Cat C15.

  11. I dont get the sound when your Hpr is high and you shift to lower gear even that i have the top engine =I
