04 yz450f header year cross?

Hello, I tried searching but didn't find the answer. I have an 04 yz450 and I pancaked the header yesterday. I'm going to try the freeze method once it's off but it's pretty flat so I'm also hunting for a replacement. Does anyone know what years of yz will fit the 04? Also, will the yz250f and 450 cross fit? I doubt it but thought I'd ask. I'm kinda broke so I'm looking for a cheap replacement alternative.


the 250f header will not fit. it is a much smaller diameter. as for other years of a 450 i know 03-05 for sure. im also pretty sure 06 and up wont fit. maybe a 00-02 426 will fit. im not 100% sure on that 1. good luck.
