What Year YZ450F Exhaust Will Fit My 2008 WR450F?

4 posts in this topic

I'm looking for a range of years of yz450f that will replace my 2008 wr450f exhaust. It looks like 2006-2009 before they get the circular midpipe in 2010 but I'm looking to confirm. It will make finding a replacement much less strenuous.

Thanks

Yup 06-09. The 08-09 had the larger head pipe with the shorty muffler. It's restrictive unless you knock out the baffles and put a pro Moto billet end cap on it.

Ok great, I purchased a 2006 yz450f silencer with a pro moto billet cap installed. Should I get the 06 header, target a larger 08/09 header, or just keep the WR header? Also, would a YZ450F FMF header fit my stock yz450f silencer? There seems to be many of those for sale cheap

Thanks!

A 08-09 YZ header probably won't fit in your silencer back section. Check with fmf on the header.
