My 2012 HD Road Glide Custom has VH head pipes, Rush Big Louie 4" mufflers, Screamin’ Eagle Pro Super Tuner installed and dyno tuned by HD dealer. All is well except the exhaust sound is not quite as deep and throaty as i would like. Larger baffles is an option, but i don't want to do anything that will have a significant adverse affect on performance. The baffles are wrapped with an insulation material and i am told that removing that wrap will produce the effect i'm looking for. Asking here if anyone has experience in doing that, does it work and is there any downside to consider? Any other suggestions also welcome.
