I never figured out how they can get away with straight pipes on a Harley, but you drive around with a hot car and open headers youll have a visit from the local police.

That being said I dont mind them, I like engines and everything to do with them, and nothing sounds quite like a Harley, I can tell the sound of a Harley from any other bike just from the sound. Blows peoples minds that I can tell the vehicle jsut from the engine sound.
