98 xc 600 was a twin motor. The xcr's were triples, and i think they also made a triple xcr in 97. Either way, no that pipe will NOT fit nor work right at all. Aside from not working good on it, that pipe is huge compared to the stock fuji pipe. The inlet is so much bigger in size, as well as the whole pipe is alot bigger.
The 440 pipe is not the same as the xc 600. The pipes are the same for most of the xc, rmk etc 600 and 700 motors in 98 wedge and gen2 chassis.
And, if you are seeing a pipe looking even close to how the 600 pipe is, that would be the 98 or so xcr 440 which agian has a completely different motor than your 93 xcr. The motors that look like that above pic is a liberty motor, and the ones in the older sleds are fuji motors. Completely different.
Long story short, It dont work ha..
