SlavJerry, absolutely oustanding mod. Could you please add this mod to the Kenworth 200 / 220.
Thank you you in advance.

Fully functional in version 1.60. For those who don't yet know how to use this mod: upon installation, it adds engines featuring straight-pipe exhaust sounds and a Jake brake; simply go to the shop, select the engine, and purchase it. Safe travels, truckers! ;) :srgearbox:

@Benders1987 it's still works fine. what's not fine though is the SCS traffic sound update causes traffic to overload total sound system, and causes other sound such as player's truck to cut in and out. however sound fixes pack seems to fix this issue.

@iceman because sound mod like these tends to be much more complicated and demand more performance (actually that's not the correct term, it's more like SCS did not provide more available resource for sound system) now this never been an issue until 1.59 which SCS actually made their own traffic sound more complicated, so we have even less resource for the player truck sounds.
