Spezial Stock Sound 1.33.x

I think we have alreay a lot of open pipes sounds, it’s good too to have quieter sounds sometimes.
 All in-game trucks (SCS) models available in the Sound mod
 Your sound depends on the engine
 Your tuning (bumper, pipes, tanks)
 Install modifications only in a single game.
– Now compatible with ETS 1.33 update
