I added V&H Straightshot Slipons to my 07 Wide Glide and the sound is waaayyyy better than stock but I've got two problems: my gas mileage is crap 28-32mpg around town and the other issue is that they are now (after a month) definitely not loud enough. I waited my whole life to finally get a Harley and I want China to hear my bike coming!! In my neighborhood, I just slow roll quietly because I'm a good God fearing man that respects his neighbors
