These headers connect to all factory emissions equipment and include necessary hardware and gaskets for installation.

    Date published: 2017-12-23
    Rated 1 out of 5 by from Doesn't fit properly The drivers side fit fine but the passenger side collector flange was off drasticlly. Ha to cut the flange off my down pipe and rotate it about 20 degrees and change the angle to make the flange bolt up and seal.
