Just finnished installing some Stillen Long tubes, Berk pipes, and intake. Driving aruond for about an hour and SES light came on. Pulled code P0420 and 0430 cat inefficiency, then cleared them and codes returned individually at different times. Even with the Berk pipes should the truck still throw the code? Also going to get tuned this week wensday but was just wondering, oh and its on a super chips 91 tune currently.

I have the exact same set up, but I haven't had any codes thrown at me. It has around 500 miles now and I'm running the super chips as well (93 tune)

What year is your truck? 4x2 or 4x4 and where are the sensors located? Before or after your cats? Did you remember to reconnect the sensors to the wire harness?

:confused:Truck is a 2010 2wd, sensors are plugged in, on the 91 tune, the pipes are from Berk so the rear 02s are behind. Just checked for exhaust leaks and didnt find any. Reset the ECU and im going to drive it for a bit :confused:

Is it possible that you damaged the the 02 sensors during the install? Did you bang them up or bend anything or pinch a wire. These sensors are very sensitive and if your crush or pinch the wires they could be no good anymore.

I made sure i took care of them, but i had my neihbore take them out at his house cuase he had a vice to hold the pipes. I dont know what he used to take them off hopefully not a 02 socket attached to a impact. Im going to ask him.

You could try to return your truck to the stock tune, and then re-tune it back to the 91. Don't know if it'll work, but it's worth a shot.
