It's possible that there are changes in MY2021 or in recent software that have an effect. Or the comparative test environment is unlike most others (it may be a difference in engine or environment temperatures, or I'll note that sound improvement is more pronounced when starting and driving in Sport+ mode). A little humility is in order ...

Sorry if I offended anyone just sharing my experience with the whole thing did not quote anyone if it worked for you happy for you. Possible that it could be better with M performance or M cars. Yes agree little strongly worded but intention was to warn others like me who thought could get a slightly better sound out of this mod. Not stupid to expect custom exhaust sound out of this please don't take it personally sorry once again.
