Codes after LT headers !
I just got my car back from the shop a couple days ago and they installed some LG streets with catted xpipe. Car sounds and feels AWESOME, but throwing the codes P0133, P0140, P0153, P0160. From what I have read I can just tune out the rear 02s correct? Which I think are the p0140 and p0160 codes. But what about the P0133 and p0153 , would those also be tuned out or is this a different issue ? I have a dyno tune appointment in 2 days so I’m hoping this is normal because then I’m going to have to reschedule this tune and take my car back to the shop , SCREW THAT. Thanks guys !

All four codes relate to the O2 sensors. Low voltage, slow response,etc. They are common when installing long tube headers because you moved the O2's further away from the stock position and they may not get hot enough to function quickly. A good tune should help and as others have said they can be turned off. That does not fix the issue. Some have suggested installing rear O2;s in the front position as they reportedly have better (hotter) heaters.
