Alright so I'll be installing my new true dual setup soon but I'm removing the cats while I'm at it. My question is do I need to have the computer tuned to do this to prevent O2 codes from getting thrown and possibly harming the engine? I don't have enough to get the tune now too and I have a deal on the exhaust which is why I'm doing it first. Should I wait to install until I can tune it?
