Would love to nix my catalytic converters. Looking for pros cons and what to do with my O2 sensors thereafter. Spare me the illegal parts and any tree hugging as well.

If you want the cats gone, get Longtube headers while you're at it. Make it worth the work IMO. And they use to make o2 simulators that would trick the comp but now you generally need a custom tune to tune out the rear o2s since the fronts will still be workin

I was going to do the same thing and straight pipe it with longtubes. Instead I put high flow cats, 3 3/4 pipe with flowmaster 40 series and magnaflow 4" echo tips. No where for me to tune my truck where i'm at that is a reasonable drive.
