Well this is a bit of a mixture of features from various years. As you say, 2000 style Decals, including the oval Head Tube Badge. However, the 2000 Decals were the wacky Glow In The Dark version, which these don't appear to be.
The last time Reynolds 853 was used for an Explosif was for the 1999 model, which you have shown above. The 2000 and 2001 Explosif are Scandium Aluminium. The 2002 Explosif returned to Steel but is True Temper Platinum OX.
The Dropouts are Investment Cast, but I would be surprised if they are Goathead version that was used on the Hot frames. I think it more likely that they are New (Dew) Drop version. The Goathead version does indeed have a Goat's Head cast into them in two places, while the New Drop have a capital letter K cast into them. Are you able to show a close up picture of them?
I'm a bit stuck as to what year it could be, but the Serial Number stamped into the underside of the Bottom Bracket should reveal this. Overall it has more in common with a 1998 or 1999 Explosif than the decals that it is wearing suggest.
