Default Exhaust system

I just bought a cheap Chinese FSN 110CC 4 stroke and need to get a new exhaust system for it and can’t find one for it online

FSN is probably a name dreamed up by the importer, If you can find a makers plate it may have the name of the Chinese manufacturer. Failing that, you can look at more common makes of circa 110cc models like Kazuma and see if any of their exhausts look like fitting. Other alternative is to make one, if only the silencer is beyond use, replacement universal silencers for motorcycles can be bought and, with a few mods to mounting lugs and possibly a bit of welding, fitted to your front pipe.

Default I found the brand it’s Yun Ba but I can’t find a simple System anywhere,,

[QUOTE=merryman;3466385] I found the brand it’s Yun Ba but I can’t find a similar System anywhere, and it’s got this filter thing that I haven’t seen on any other system and can’t figure out what it’s for

"Filter thing" looks to have a rubber pipe on it so must not get all that hot. Could be a breather, going into exhaust rather than inlet, or could be some sort of exhaust gas recirculation but rubber pipe would then get hot. Google fetches up even less about Yun Ba, other than them being a manufacturer of alarms for ATVs, so either they didn't make many ATVs or you got that name from an electrical component on the bike rather than it being the bike's make. Front pipe doesn't look shot. If it is serviceable, paint it with heatproof paint and put it back, fitting a silencer that will fit both pipe and the space it has to occupy.
