Can I gut out my first set of cats? Would it show a code or will I have any more problems? This truck is a stock and I don't know who to talk or do to!

Leave the primarys on and you will have no emissions, or Check engine light issues

1/ SCT Tuner and it will turn them off
2/ custom flash
3/ simms elec or mech.
4/ sparkplug foulers
5/ tie up to frame to ground out.

The cats can be deleted, but the front O2 sensors are needed. The rear O2 sensors can be fooled via several methods. I was under the impression that tying them to the frame merely allowed them to read clean air, not short them out. I personally use the sparkplug anti fouler, and I have no codes.
