03 YZ250F exhaust fit onto a WR450F

Hi. Can someone please advise me. Will a 2003 YZ250F muffler fit onto a 2003 WR450F. The brand I am looking at purchasing is called a DEP MUFFLER.


No it will not.

Hi. Will a yz450f 2006 big gun exhaust fit a wr450f 2003 ? will other year and models fit. I do not need the header pipe, only a muffler. Thanks

The mounting point on the midpipe changed on the YZ from 05 to 06 when the aluminum frame was introduced. The WR didn't get the aluminum frame until 07, so the exhaust mounted the same. The silencer for an 03-06 WR450F aand the silencer from an 03-05 YZ450F mount the same. The headpipe diameter remained the same thoughout those years as well I believe, so any silencer from these years should work.
