I don't know hwere the mufflers were made but they are not straight through pipes.
When trying to clean one out we found two "Baffles" with holes that do not line up inside the muffler. I expect that the volumn of the muffler and placement of the baffles is not ideal for the larger displacement. We saw a significant drop in RPMs when the muffler was put back on. The drop was around 300 RPM.

If the mufflers are inline with the cylinder they will con cause as much drag as the old Mark5 mufflers which were mounted on the side of the engine.

Somewhere around here I have a magazine article that shows how to do a repair job on our mufflers. Not too involved. Basically shows how to cut it open do a fix, and then welding it shut again. It shows a good cutaway view of the muffler internal arrangement too. As soon as I can find it, I will scan and post it here.

Ok, I think someone asked this recently, but I'm going to ask again anyway. Were these mufflers an actual Rotax part, or were they an aftermarket muffler? Where did these actually come from???

I think that this company, Leading edge airfoil, has it in stock. Their catalog has a lot of goodies and information in it, and makes a good addition to a collection.

I do get LEAF's catalog but their mufflers all have a different intake and exit than ours. Now that's not to say they aren't Rotax mufflers we have, they may have just been built specifically for the 185 at some point.

Just not sure. Dale, you up for some muffler info?
