ILeftNJ, Looks like you are having fun! The Dunstalls you installed look good. They look very similar to the Norman Hyde Toga's, which I have used on some Bonneville's and like the sound of. Since your Bonneville is a 2015 model, it is electronic fuel injected (EFI) and does not have carburetors. In this case, your computer adjusts itself for the change in exhausts. There may be a better computer "map" for your setup, but you would need to research that and be able to reprogram the onboard computer. If the bike runs well as is, I would just enjoy the ride!
