YZ250 too loud

As title says, 2011 yz250, just a bit loud (still on stock exhaust). My preference I think it is a little loud, but I also ride at home and have to considers neighbors as well as my own family. So, what’s the quetiest silencer you can get for these things? Bike only has 40 hours, I would almost guess the packing is just caked in oil but I’m not sure since previous owner said he never used the stock silencer much, and it’s a nice running bike. My 23’ KTM 125 is quieter even ripping it hard for reference, maybe I just need to repack silencer? Thanks for your answers everyone!
