How long after the install did you guys with Cat-Less DPs throw the CEL? Was it immediately?

I got CEL on my catless downpipes the next day after installation. I fabricated am O2 bung (similar to what supersprint offered with their F10 M5 downpipes) and it also threw CEL after 4 days.
In my opinion, I noticed no change in sound after installing downpipes (even catless). However my friend's F10 M5 did increase the sound significantly. He has the full supersprint exhaust. He installed the downpipes at a later stage and claims the increase in sound is very significant. I guess this is because of the different turbo setups in the M5.
