As the other guy stated, even though he has HFC, he got a cel, playd with the 02 extenders and got it to work.. Reagardless if you have cats or not, a CEL for cat inefficiences is what it is.. If you can alter the signal read by the ECU you should be good to go.
What dont you get? This isnt a competition or an argument. You have yet to list what x pipe you have and what mechanical 02 delete you are using. I can report the fabspeed extenders didnt work in the dinan mid pipe and didnt work in the RPI x pipe. Its to the point where i'm willing to make a serious bet with you that there is something else going on.
