So i got my Catless downpipe installed today on my 2013 E92 335i and there was no check engine light at all and there still isn't any check engine light , I've driven about 50miles and still nothing . I'm tuning wth MHD this up coming weekend btw

Any sounds clips? Did you have to unbolt the steering rack out of the way?

Check engine light will come on soon enough.

Venders say that many don't have problems with CEL but I think this is a misleading statement. The likely complete answer is that "Many customers (worldwide) do not have problems with a CEL on stock software" In reality it appears that the BMW USA catalyst efficiency maps/specs are much tighter than other parts of the world. Meaning a XYZ high flow cat will pass an OBD2 check in Europe but not in the USA.

Commercial tuners won't touch that issue because of the enormous legal liability (modifying the ECU readiness efficiency specs). One thing to turn them off "for offroad purposes" but entirely different to show ready on an OBD2 check.

Which vendor says they have no problems with CEL with catless downpipes?

Same here OP...just installed my catless DP and FMIC 24 hrs ago and CEL pop in my dash..cleared it with my COBB AP...so far so good,no CEL...But for sure when it comes this year for emission test it will show on the OBD TEST and I will fail for sure in my state.Hate to take the DP every year just to pass,but I guess you have to "pay to play"
