    4 Stars   Fit great but pretty raspy
    By on 6/12/2016
    Bought this to go along with the BBK aod headers that went in great. X pipe fit perfect but gonna take some time for the new exhaust note to grow on me. A lot more raspy than I had hoped for.

    Yes, I would recommend this item to a friend!
