Does anyone have any pictures of their engine installation and how the cowl was cut to accommodate head and muffler. I am currently trying to finish up my plane with a Saito 100 engine mounted horizontally. The Saito came with the "new and improved" muffler and I will have to pretty well butcher the cowl to make it fit. The Saito straight pipe coupling is perpendicular to the engine. The pipe and muffler will require a huge hole so the cowl can be installed. The muffler can't be screwed on after the cowl is installed. Hindsight is 20/20 but I probably should have invested ($90.00 USD) in a Pitts muffler for the Saito. Alternatively, I could have tried an inverted installation (didn't want potential problems with my first 4-stroke engine).

I think I will probably see what I can do with the standard muffler for now and order a new cowl for the next attempt. Just want to get it in the air for now. Pictures, ideas and suggestions are welcome!
