Hi guys. I need some assistance. I wish to remove the Catalytic Converter by breaking off the ceramic from the inside and run the vehicle without the CAT for track use. I forecast the issue of P0420 & P0430 Check Engine Light transmitted by the rear O2 sensors. How to fix that issue without ECU flash/re-tune? Will appreciate your assistance in this regards. Thanks!
