I have the edelbrock exhaust that latus harley in gladstone modified back in 2003 for the lightning. It was the first aftermarket exhaust made for the lightning they do not make these anymore. The sound is unique and very loud. Louder than any buell ive ever heard. They are in great condition just too loud for me. Anyone out there want to trade their exhaust for mine? Im looking for aftermarket. I have a video of them if interested email me at dave_spencer2@hotmail.com
