CL1PPED63s

Hey, I got a 2018 C63s a few months ago and I am finally ready to start modifying it. I just purchased SSR Downpipes but don't know what to do about the check engine light. I know you're usually supposed to get a tune but I dont want to crazy with the power yet. Is there anything else I can do to throw away the CEL? Do o2 spacers work?

You need a stage 2 tune my man. Good luck.

you need catalyst in your downpipes that will fix it.

You can try the spacers or a tuner can turn off the O2 sensors.

All you need is 02 Spacers, it worked for me!

May i ask which 02 spacer did you use ? also how many 02 spacer you need is it 2 or 4 ? and also do you need to do any ecu reset or unplug the battery and plug it back on ? let me know thank it would help a lot <3
