I had a set of Cobra Neighbor Haters put on before took ownership of my 2019 RGS. I ready some very positive reviews, and if I do add headers, intake etc. later, they should sound even better. Road bikes with a few different slip on options, but like you - didn't want anything overly loud, just a good deep rumble. Also, parking lot evaluations are great, but I was concerned about the drone on highway speeds for 2+ hours of riding. During my test rides some sounded awesome, but I knew I couldn't handle them for an extended ride. I'm very happy with my decision. Also, all my test rides were at dealers.
