That's the wrong J-beam file, that one's the engine, and only affects how the exhaust reacts, not how it's positioned The file you're looking for it the one that has the same name as the mod, this is the "main" one, with the node locations and all. Once you open that, search for "exhaust" then keep going down until you see a exhaust node that's connected to another node, like this: {"beamSpring":120000,"beamDamp":12}, ["engine_Gearbox11", "exhaust_6" { "isExhaust":"mainEngine" }], The first connection is "engine_Gearbox11" in this case, and the smoke will flow from that node, to the "exhaust_6" node Pull up the locations of the other nodes with the in-game debug, and simply change the "exhaust_6" node to one in the desired location EX: {"beamSpring":120000,"beamDamp":12}, ["engine_Gearbox11", "a23" { "isExhaust":"mainEngine" }], That's the easiest way to do it.
