Can anybody please tell me the measured db rating of a stock yz400f with the stock exhaust system?

Also, the stock yz muffler appears to have a turn-down tip. Are there replacement cores that will fit the stock muffler to reduce noise levels? I know they exist for the WR muffler but not sure about the yz.
Thanks
