Systems and methods for concurrently destroying old pipes and installing new pipes in their place. An exemplary embodiment is a pipe bursting and replacement tool that includes a body and first and second connectors. The body has a shape that generally tapers from a smaller diameter at the front end to a larger diameter at the rear end. The taper need not be smoothly increasing, but may alternatively be stepped. The first connector couples the body to a pulling rod to and allows the body to be misaligned with the rod to relieve stress on the connection between the two. The second connector couples the replacement pipe to the body so that the replacement pipe can be pulled behind the body into the space previously occupied by an old pipe that is burst by the tool.
