OS Max Muffler Replacement
 

I have an OX Max 90 that had a non-stock muffler on it. The muffler was held on by a hose clamp, and the other day, it came off and I couldn't find it. Since the muffler is no longer in stock, I have to either go 3rd party or find a used muffler. Can you tell me what the muffler number is for that engine so I can find a replacement? Thanks!

Pehaps a picture will help. This is what the exhaust port looks like on the OS 90. Looking at the discontinued engine list, the only os90 that I can see is an OS91FX. Since this is the only OS90 listed, then I assume that it is the same as my engine which says os90max. IF this is the case, then the part number is OSMG2840 which is available from several stores. All I am looking for is confirmation that this muffler will work for my engine. Thanks

It's the old .90 FSR. You'll have to see if you can locate the muffler adaptor and parts online somewhere. A muffler for the 1.08 FSR may work out.
