    Thats some muffler

    When the muffler arrived it had no padding in its cardboard box. So combined with its weight the inlet and outlet pipes werte slightly out of round. You can fix this with a thick wooden dowel and swirl it around. I also used channel lock plyers to slightly flange it out where it was worse.

    When in place I needed to put a block of wood at one end and hit it with a mallet to hammer it in, it was very-very tight.

    All in all it was a almost exact replacement for my Jeep (slightly narrower than factory) but did the job right.

    No moisture drain hole if you care about that.

    Only took off one star for the lack of padding in shipment, the end product seems good quality, hopefully it won't rust out too fast.

    Pros: I got it in, hurah!

    Cons: Required a bit of flanging, no moisture drain hole.
