so i looked around and it says that it is either o2 sensor is shot or my cats are clogged... but the xpipe is brand new so i doubt the cats are clogged.

So what do you guys think i should do? just clear the code or hwo would i check the o2 sensors?

Catalytic Converter Effeciency Below Threshold (bank 1). I get its companion bank 2 code, P0430, about once every 6 months. I reset it and it doesn't come back for a while. I don't know why I get it I'm running long-tubes and the rear 02s are supposed to be turned off.

There is a ton of stuff that causes it including faulty injectors and spark plugs. I'd try reseting it to see if it comes back.
