db eater remove what penalty?

hello how to recognize from the cover I am interested in the punishment you get if you remove the db eater from the exhaust… I ask the question because yesterday I built a leo vince exhaust under my fazer and of course also made a test trip without the db killer (who wouldn’t have done that) … but for my feeling it was too loud and disturbing… but I’m interested in it… I looked here in the forum and also at google but somehow contradictory answers found… until the middle of 2006 there were probably 50euro and 3 points after that the §18 stvzo was deleted without substitution and there should probably only be 25 euro there but then also people who claim something else… so one knows more precisely? in advance already thank you
