1999 Polaris XC 600 exhaust

Hey folks. I?m looking on the Polaris website as I need a new pipe. I found a pipe on kijiji for sale but the guy said it?s off a 2003 700 SKS 144 (which I couldn?t find on the Polaris website). Anyone know if this will work with my 99? All the 2003 700 sleds have different product numbers than the 99 (1260764).
Thanks in advance
