I don't think anyone sells them in peace's, not that I have seen anyway, but I did replace a section that got damaged on my friends lift by the lift arms. I just cut the section out and went to a custom muffler shop and had him make me a peace that he expanded on the ends to fit over the parts of the old muffler that was left I had to put clamps on. worked just fine and wasn't all that expensive if I remember right, my memory is shot but I am sure it was under 50 bucks.

and one big pain in the ass when it doesn't
