New downpipe needed for 1998 model, what can i use?

Yes, downpipes from any FZS 600 will fit (NOT the FZ6 though)

Sandy bike spares are well known and are usually about the cheapest for new stainless steel. Most will recommend Motad though as they have the balance pipes between cylinders 1+2 and 3+4 which helps with the midrange
