Forum rules
SCS as a company do not wish to have paid mods on this forum. While we understand that not all paid mods use the Intellectual Property of other companies/people, it is very hard to moderate what is and isn't acceptable when money is involved. There are also concerns that it could look unfavorable to potential work partners going forward if SCS allow mods that may potentially use unlicensed branding.

This mod is CAT C15 6NZ engine straight pipe for some SCS trucks and many modded trucks.
(Some SCS trucks will don't support because there's no C15 engine in real trucks,
also if this mod doesn't work on any mod truck tell me so I can make it support that truck)

Feature:
-CAT C15 6NZ 435, 500, 550, 595, 625 engines with straight pipe sound
(625hp engine also replaced on SCS pete389 and kenworth w900)
-Smooth & Realistic engine & exhaust sound
-Custom sound attenuation for more realistic sound fade off
