Posted for Pekka Aatolainen in Finland based on his request for LOBO help:

I have "old" 320 nearly completed, but I still need exhaust system for it. Engine is 320 D3G ( carb. Model) Haven't get any reply from Lancair, so maybe You can give me some advice where I can get this complete exhaust for my project. (Aircraft Spruce cannot help, at least, that's what they said.)
