I know the less loud clicking is the injectors, but is the louder more obvious clicking something I should be worried about?

Recently purchased 2013 335is with now 28k miles. So far have put full ceramic tint 15% everywhere except windshield 35%. Just did the VRSF muffler delete today, maybe one day will go with a full exhaust setup, but I didn’t want to be insanely loud we will in the future.
