Yz exhaust on 12+ wr450f

Is there a yz slip on that will fit the 2012 and up wr450f? Not a whole lot of choices out there for exhaust so I am wonder if an older yz fits....big gun exhaust lists the 09 yz along with the 12 and up WR as same part number but fmf and others do not. Can someone clarify.

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.

I have a gytr slip on which is basically a powercore 4. Also DR D is the Yamaha R&d guy... He makes good stuff too
