hey guys i bought myself a 03crf today and i got it for a awsome deal so for the money i saved up i was thinking of getting a exaust system for it but i really like the way the new 04aftermarket systems can change the weight around. So are the exaust mounts on the 04 different than the 03 or are there other reason i should not be able to perform this mod?
thanks for all the help guys.

I don't have the 2 bikes in front of me to check, but FMF lists different part #'s for the headpipe on the 02 vs the 03. The mounting holes may very well be in the same position tho.

Actually the header sections are the same from '02~'03 it is the mid pipe that differs as the mount location on the subframe is relocated in '03. Easiest wat to check would be part numbers on the subframe. If the 03 and 04 are the same it will fit.

I could be wrong but I Thought the mid pipe was a bigger diameter on the 04'crf It looked huge to me when I bought it and the guy at the shop said "yeah look at that pipe diameter I think its wider than on the 03'

Well yes and no. The header section on the '04 is longer and swooped down to move the collector can(silencer)closer to the center of the machine. So the larger part of the mid pipe is moved forward. Mass centralization. When replacing the whole sytem one only needs to line up the mounting holes. Thus a '04 sytem would fit on an '03 if the mounts were in the same location. Which can be assertained by same part numbers on sub frame. The '02 is the only different one I do believe.

i just looked on service honda and the 02 subframe number is
2002------(50200-MEB-670)
2003------(50200-MEB-770)
2004------(50200-MEN-670)
so i guess this meens my 03 wil not receive and 04 pipe like i had planned on unless someone has tried and it worked

If you replace the whole system, it will bolt up. I even ran an '02 exhaust on my '03. Had a tab welded on the subframe. The mounts are identical from '04 to '03.
