What is a 'YZ slip-on' ?
You mean a louder, less restrictive muffler?
It's not a YZ so the subframe mounting and mid mounting would be different.
FMF, Dubach racing, ProCircuit all have options.

The part number for the WR muffler didn't change in '12. YZ mufflers up to 09 should fit. The YZ headpipe is fatter but the aftermarket mufflers usually come with a collar to fit the WR header, I think.
