If you don't have emissions...get the catless one.
If you do...there is a chance that the cat code will still pop up since it flows better than a factory converter. You will only notice a little difference in sound with the catless downpipe vs. the one with the HFC will almost sound factory.
If it were me, I'd get the catless one...then get a tuned PCM for it and have the rear o2 code removed from the PCM so it won't go off ever again.
