I am a new dodge owner. Have done a few small things to gain some power, I have a 2008 hemi 5.7. Was thinking about removing the catalytic converters, but I don't want my truck to start throwing codes and not running right. I have heard of non- foulers? Not sure what they are or how they work. Does anyone know if the truck will still throw codes if I just cut the cats out, knock the insides out of them and weld the pipe back in place with the 02 sensors in place still?
