2003 YZ 450F exhaust question

[capt.270]

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

Yes it will with modifications.

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 ?

I'm not 100% sure on the header but 03-06 wr fits as well.
