[GianlucaM235]

I’m going to be installing my catless downpipe this week on my m235. I’m not planning on tuning the car but wanted to get rid of the cel. Has anyone used 02 spacers with success? I just don’t want the engine light, I don’t need to pass any standards. Also do I just need one 02 spacer, and would that be to the turbo side or exhaust side sensor because there is two of them? Thanks for the help.
