If I remove the catalytic converter from my exhaust, what happens? Not talking about the legal ramifications. I mean the O2 sensors, trouble codes popping up, etc. I have read in MVS someplace that just leaving them in is needed, but maybe relocating them back a bit? I don’t really know what will happen but I want it off.
Another question: Will it cause any problems with the valves (exhaust) or anything else?
