hajluk, it's pretty easy to do it for yourself (I did just now). I can' and won' publish it, but I can help you. It's really just a few seconds. 1.: subscribe the V8 open pipe mod on workshop (the one made by Ro0llo) 2.: find it in your library (it's not compressed, so you don' need anything but notepad) (...\Steam\SteamApp\workshop\...) 3.: create a new folder and name it "scania.r700.new inside the def folder 4.: step one back and copy one of the other truck's def's content (f.e. def\scania.r\ 2 sii files) into the .r700.new folder 5.: open both the original r700 interior V8 (mod\...\def\truck\sound) and the new one you just copied with notepad and replace the engines with the ones you need + on the 3rd row fix it to v8.scania.r700.new.isound 6.: repeat 5 in exterior_v8.sii 7.: enjoy p.s.: I'll contact Ro0llo to update it on workshop, so you can just wait
