    They are not direct fitments

    I purchased these exhaust on a Friday and got them on a Tuesday great shipping time but when I came to put them on the muffler mounted fine but the tailpipes would not go over the axle luckily I can weld so I had to buy couplets and cut the tail pipes in half then weld them back together where they fit, if you don't know how to weld take them to a shop but after the install they are a good nice exhaust the sweet spot is 2k rpms
