My guess is that you will get many opinions stating both, do and don't. Do you know what was done when jetted for cobras? I had mine rejetted when I got glass pack mod, (dragon exhaust). The mod gave me the option to run with or without the baffles that came out of the mod. Tech wanted to dyno and jet it for how I was going to ride it, so he felt there was going to be a difference if I ran baffles or not. Tech is pretty good and has done many of racing bikes, so I believe what he tells me, if it matters that much on a cruiser, ridden for comfort
