Catless Downpipe and Tune

F87Daily · 07-08-2019, 12:51 AM

So, I own a 2018 M2. Looking to install my catless downpipe and was wondering if anyone in the Bay Area. CA. knows how much it would cost to just do a tune to get rid of the CEL. A good estimate would be highly appreciated. Also, if you can give me some recommendations on tuning shop that you can trust.

You can tune it yourself with BM3 and disable the CEL for the o2 sensor

Thanks for the info! Do you know if BM3 will be a problem when warranty is in play. Will my warranty be voided if I used the program?

Yes, warranties are voided with a tune (if detected) which is why many people opt for catted downpipes.
