    I have a 03 Heritage, and have screaming eagle exhaust, but want a little more out of her, I have heard of these baffles, they say they are very good, would it take a remap to install these on my scooter??, I am thinking about getting myself a set and check them out, and I am new here, so, Skully is back, and would like to have some input from someone who has used or is using these baffles....Many Thanks,,,

    Haven't used the baffles but typically if you change exhaust and have EFI it will require some modification to the map but that's not 100% the case

    Going from stock to aftermarket (OR hd SE) requires a map

    Going from HD SE to a pro pipe will need re-mapped

    Changing baffles may or may not need remapped depends on if you were mapped rich or lean.

    You can try it and see how the bike runs dyno tune with snifter up the pipe is the best way.
