Big Gun also has a system.
If you get a slip on style you will need an adapter since the WR head pipe is smaller than the YZ's

does any of them make better low end than stock and mid range.tons of top end in stock form for me just looking for more bottom
I'm going to say the slip-ons are your best bet since they keep the smaller head pipe...
