Looking to replace the muffler on my 2025 ADV5 . I know it won't lower decibles much but tone makes a big difference . But RPM Powersports says if you put theirs on it is no longer street leagal . Anyone know what's up with this and would it pertain to all aftermarket mufflers ? HMF doesn't say anything but are more than double the cost .
