488gtb turn off cel without tune

Hi everyone, I have a question regarding about the IPE 100 cell catted downpipe on my 2018 488GTB. I want to put it on but I am afraid that it will trigger the CEL. Is there anyone solution to turn off the CEL WITHOUT a tune? I called 2 different shops, one said they can put a O2 spacer and it will most like work which cost 300 bucks, the other shop said I can either flash the ECU to turn it off for 1000 bucks or buy a Capristo OED which is 1500 bucks. Which one should I do?
