The 02 header & HMF are interchangable but are very different. Look at the length of the headpipe where it joins the collector. The 02 has very short headpipes, where as the HMF tried to go as long as possible before going into the collector (like the 03 headpipe).

Those pipes are not known for the best dyno hp numbers... in fact I think they are the worst in comparison but its all relative. The fmf can that was on there was the quietest and most restrictive offered... they last a long time tho. When you stuck a hmf on there, it was a pretty good gain along with more sound and less weight!
The full big gun has even shorter runners to the big pipe, they are very loud especially when they need packed which is often.

I think you mean '02 or HMF? If so the HMF is a better performer but maybe not for the money they charge for it. The FMF Ti pipe would be the highest performer of all 3 of the factory offerings and anything made on the aftermarket with the possible exception of the duals that have been made up recently.

But which header is better the hmf or the stock 02, i looked at fmf headers(not for cannondale) and they seemed to dump the two pipes together more like the 02? so whick provides better flow?
