My friend just gave me his old fmf factory fatty. He had a honda cr250. Im not sure what year. My dad has a 2002 honda cr250, and the pipe fits good into the frame, no clearence issues, the bolt holes all line up, but the part where it connects to the engine ( exhaust port? ) is the same size as the pipe! I was just wondering if there is some sort of flange adaptor or somthing? Or is this just the wrong year pipe for my bike? Did honda make the exhaust port smaller or somthing after 02? Please help!
