Muffler cross over
 

My O4 MC 250 currently has an FMF Turbine Core on it. The end cap is pretty mangled. I've added rivets and it's still sloppy. I've found Turbine Core 2 end caps on eBay that look similar. Anyone know if they'd rivet into place? Follow up question: Are there any other spark arrestor mufflers that cross over? KX stuff maybe?

Many of the FMF end caps are the same but you will need to get the right size hole. I think the 125 mufflers had a smaller diameter. You should be able to call FMF and ask them for the part number.

I saw many that looked close to the GG version but mounting points were in different locations.
