I have a DSP system on my YZ timed WR426 but it's too loud. Thinking of putting on a stock YZ muffler. Can anyone give me an idea of what the power/noise is like with the YZ pipe

Really loud! They wont pass the 94dbl level tests at silver lake in Mi. I put a WR pipe on mine that I opened up a bit for the dunes. It is a bit slower at low rpms but still very fast.
