Code P0430
I was wondering if I can permantely delete the P0430 code which is Catalyst System Efficiency Below Threshold (Bank 2). I currently have h-pipe with cats, im eventually going with off road pipes. So the two things I have to check is exhaust leaks (How do I check for that) and bad 02 sensor.

Do you have longtubes by any chance?
If so you are supposed to turn OFF the rear 02 sensors in order not to throw cat eff.
codes.
I don't think you can do it with a SCT tuner or whatever.
I believe a professional tuner has to do it for you meaning dyno tune or
ordering a tune online.
IF you have a tune ask the tuner if he did this or not.
Odds are he did not.
