Wanted - 503 exhaust/muffler assembly

[Cass256 4]

I have the header, gaskets, and springs, but I'm missing everything else. Anyone got one for sale or know where I can pick one up?

There are a number of versions of this exhaust, best option is to get hold of a LEAF catalog or similar and get apart number or drawing and try again. If you know what you are looking for, sometimes EBAY. Search ROTAX exhaust. They are not specific to the 503. 447 503 532 and 582 will fit if the version is correct. Depends to a large extent on the airplane.
