..:: sleestak ::.. if you look at dynos between the two, the HFC and the ORP are right about the same, its just a matter of where you see the power. IIRC, the ORP will give you gains on the high end and the cat will give you more power in the middle.

IMO you will be better off with the cat, have a better chance at passing emissions (PM sent about that), and it will sound WAY better. I have hear clips of ORPs on stock focus exhausts and its not that impressive. I have a cat on mine now and it sounds nice...a lil louder, but just about the same tone.

scrammer super HFC? hmm.
you will not pass emission with an ORP. you should pass with a HFC. this is based on sniffers.
if you have a tuner that eliminates the MIL, an ORP will be safe to go through a OBDII test. but they have the right to sniff.

egman2005 you might get away with a visible inspection depending on how good they look. But in theory you wount pass emissions. With the HFC you will pass emissions. and cfm did a test to show the difference and the orp and hfc were very similar in performance gains
