Hello everyone. I was wondering, would the exhaust from a yz250 fit and work properly on a wr450? i got my WR with the baffle removed from the muffler so now it is straight out with no sound restriction. I know where i can get an exhaust from a yz250 for free. will it work on my WR? I dont mean the whole header and everything. im just wondering about the second half of the pipe with the muffler on it. the attached picture is the exhaust that i am wondering if it will fit on my WR450. I was told it came off of a 250 (which i believe was a YZ). Im not sure if years matter or not.
