    Default Shorty vs Long vs Stock HEADERS

    i was hoping sombody could educate me on headers, clearly anything above stock manifolds will make a difference in power but im curious about the fuel efficiency and sound to go along with the power increase.
    as well as the matchup -
    short headers or long headers?
