Got this on a purchase, was told it was a BME 50, Runs like a champ, just need to get the muffler fixed, (one of the exhaust tubes) came a little loose...

But when I got curious and was searching just to replace the muffler, I noticed that this may not be a BME 50?

Here are some pics for you guys to help me with......

The mufflers on Chief Aircraft dont match...Chief's pic shows it square and my engine is rectangular. Bolt pattern looks like it will match, but may not seal...

Engine fires up on one flip, flys great. Just dont think or know if its a BME. I would like a new muffler, but I could fix it if I had too.


Any ideas?
