im going to remove my cats and put in straight pipes. Right now the cats are hollowed out and im wondering if i put straight pipes what do i do with the O2 senosr? i have no check engine on now, but if i unplug the O2 will it throw a code?
yes, you cant run with them unplugged.
you can use the Predator to disable the rears, however when it comes time for inspection you wont be able to pass (if you have to deal with this in your state)
you must have an 09 if the Sensor bung is located in the cat....
you can either have a bung welded into the new pipes that youre going to have put in,
or you can spend the coin and get a perfect fit of JBA catless midpipes that come with everything tapped and ready.
but like i said, you HAVE To keep the O2s plugged in
