G'day and welcome.
I have the same set up as you, but I did make one change. The Classic has the cone shaped tips on the exhaust pipes. I replaced them with the slash-cut ends. The sound is VASTLY improved. It sounds much deeper, with enough noise when you pull open the throttle, and just the right sound when cruising.
I was surprised at how much the sound improved with that one small mod. You could try removing the cone ends just to see how it sounds and then go from there.
