I have a yz426 which runs a ProCircuit system. This will never pass any noise tests. With this in mind I have just got hold of a WR system from e-bay. I have also got a stock header and Arrow Silencer. I might run with the Arrow silencer and stock header and when I fail a test I will stick on the WR silencer.
I have a couple of questions I hope somebody can help with....
What is the db rating for the WR pipe with and without the insert?
How bad will it make the bike run? I'm not concerned about overall power as it has more than I can handle.
