OK here's the deal. I live in North Carolina and since my 1993 SC 400 is 15 years old + I don't have an emission test. So I can delete the cats on my car. If I do can where does that leave me with O2 sensors. Do I need them? Will the car function with out them? Good idea? Bad idea?

 

im pretty sure you need them, you might have some issues when the pre cat and post cat o2 read the same but i could be wrong

 

Yeah I'm thinking with the O2 sensors and the Maf I made need them

 

I removed all of mine but left the resonators in place and stock mufflers. I had the local mufflers still on and had no problems with the 02's, just left them in place.Every car will react different. If you remove you might throw a code and you might not. Only way to know is to try and see.
