If you are changing from a stock WR system, then you should get a significant improvement from the pipe. On a YZ450, the PowerBomb has the effect of making the power curve higher at the low end, slightly higher or about the same at peak, and about the same or a bit better at the top end. It should do fine on the WR, but don't be surprised if you have to work on the jetting quite a bit.
