I can confirm that my 2019 is def louder than my 2018. The prior version was near silent. I think Robs video sounded super loud though...I wouldnt say mine is that loud, but its def got more noise which is not faborable. The ride itself...its pretty different handling. Then again, I also modded this more that the last one I had for maybe a week.
I test rode a '19 here in Colorado at a dealer and it was much much louder than my '18. Not terrible but would rather not have the added noise. The 18 is near silent unless really pushed hard up a hill.
