02 4.7 cat delete and potential problems
 
i have an 02 dodge ram and i am doing a full exhuast from the intake, headers cat delete and stainless pipes and muffler. I was looking into getting a programmer too. there is an O2 sensor before and after the cat and with a cat delete, i was wondering if was going to throw a code, ruin the mileage or anthing like that. And im assuming i need to new O2 sensors to put in.

You don't need new 02 sensors unless they are faulty. You likely have 02 sensors in the manifolds and after the cats. The ones after the cats are only for emissions and don't effect performance, mpg, etc. Removing the cat won't harm anything but it will throw a code. There is a way to fix this with spark plug non foulers/anti foulers on the rear 02's.
