If I remove my cats can I just unplug the 02 sensors and do I need a new tune?
If you decide to go head and remove all 4 cats, then you will need to leave the rear two O2 sensors in place and just unscrew the front O2 sensors (don't disconnect) and wrap them up somewhere out of the way.
ya got that backwards, the front 2 are for AF - leave them in.

I put the catless mid pipe in, hooked up all the sensors back up, even ran it through emissions and passed.
I live in maryland tho. never has thrown a code.
Are the catless kids custom made.
Do you feel a big difference in power?
better throttle response, def let the truck breath.
I think maryland laws are 5000.00 for not having cats on.
