This mod is Volvo D13/D16 engines with open pipe sound for all SCS Volvo trucks

DISCLAIMER: Although this mod has D16/17 engine, it shares the same sound as the D13 as I couldn't find enough samples.
But because I know people will want to make this compatible with D16 so I add it anyway, and will try to make actual D16/17 sound in the future.

Version 1.5 Changelog:
-Fixed the dreaded bad take off torque
-Convoy optional is now turned to on
-Bank rebuilt, though with the same samples
-Swapped engine brake stage 2 with 3 (only jake in 2nd stage, jake and exhaust brake in 3rd stage)
Note: After this update I don't think I'll be updating this mod for a while until I could find usable *proper* FH16 samples, 
otherwise there probably would be minor fixes here and there as needed
