I presently have a WR426 with a YZ pipe.
I am wondering if anyone knows if there is a replacement insert (or endcap) for the OEM YZ exhaust that would make it a bit quieter?
If not an insert, any tricks from the YZ crew? Its nice to get away from that uncorked WR sound at least...but anything quieter and non-hp-reducing would be awesome :)

I have a BMP insert in mine. It uses discs like a supertrapp so you can dial in the noise and power to your liking. I know another company makes them also, but the name escapes me. Cost for the BMP was $120.

Thanks PK, I will take a look around and try to dig up some info on them. Did you per chance get yours online somewhere?
