I came across a post (somewhere ?) that the 2022 TC horn is much louder than the 2021 stock first edition version. The BMW dealer if fact said the horns look similar but have different part numbers, that's all he had to offer - Part numbers FE 61337921753 and TC 61337924403, can anybody offer any insight please? Don't want to go with an automobile horn, just stay with BMW motorcycle OEM.
