CRF450 Exhaust questions: trivia help needed


I need a stock header and exhaust for my 2004 CRF450R.


I cannot recall if 2004 had its only stock exhaust fit. In other words, will any other year fit the 2004 CRF450R????

If memory serves me correctly - each year, except 2007 and 2008 had differing exhausts - due to where the midpipe connects to the subframe.

I need your help!

Not sure on the fit but if you are near Tucson I have a stock pipe for you. No header though.

check the FAQ's STICKY on the top of the 450 forum... they have the years of what fits what i believe.. hope that helps

i just went and copied it.. i dont know if this will help you or not...


(Needs to be completed)

02 head pipe the same as 03, muffler wont fit later models


The mounting points on the engine and subframe are the same,but you have to use either the entire 03 system or the entire 04 system,the head pipe is shorter on the 04 than the 03 and the mid pipe is longer on the 04 than the 03 cheers

If I am reading this right, a complete 2003 system will fit either a 2003 or 2004 and visa versa.

In short, I need to find a complete 03 or 04 to fit my 04?
