Thought it's gonna fit here. Sm04, Sm41 and something else that I forgot to wrote down. Waiting for repairs in southern Poland.

Today I finally partially painted my Dnepr and after almost 2 years of fighting with every single part I took it on the road.

I was surprised to discover that there are flat engines but mounted longitudinal to the frame.

I have Dnepr mt11. I need help with finishing exhaust. I have pipes that goin out of heads and decompression chamber (this curved part on the bottom of the picture) but I can't get muffler like the one on the picture and I'm planning to just make one. Does anyone have this type of exhaust installed? I know that there were some Dnepers that came out with 2in1 exhaust and also that some people modify their bikes to have this type of exhausts but I don't know the dimensions of muffler to install here to not choke the engine. Also another thing is that the side pipe, the one with the decompression chamber is going into muffler in 90° and I'm not sure if that would not make exhaust pressure from second pipe slowed down or something. Anyone has this type of exhaust or have their Ural or Dnepr with 2in1 exhausts, even diy and can give some info in this matter?
