    I bought my CRF 250L with a FMF Q4 exhaust. It’s got a great look and is way lighter than the stock, but after a days riding with it my ears were ringing. Put my stock muffler back on today and it seems whisper quiet in comparison ! It’s a heavy unit though, so just glad I’m a light weight unit !

    Sounds like you need to repack the FMF silencer. You should notice a big difference after repacking.
