I have yet another question about the exhaust on a 2003 yz450f.  will a exhaust system from a 2006 yz250f fit a 2003 yz450f? and if not why not? like are the mounting points different? or is the diameter different?  the exhaust I'm looking into is a used fmf powerbomb with whitebros silencer. thanks

04 and 05 450f exhaust will work with the 03, and that's it....unless you want to modify it to fit.  So just find a 03-05 setup for a 450f ;)
