1. A system for establishing a bypass flow path within a wellbore, the system comprising:
a plug assembly extending from a first end to a second end and having:
a plug body;
one or more bypass ports extending from an exterior of the plug body into the plug body to below an engagement surface of a dart body;
a bore extending through a portion of the plug assembly;
a wiper dart configured to engage with the plug assembly and configured to be run with the plug assembly within the wellbore, the wiper dart having:
the dart body; and
a dart nose attached to the dart body via an attachment device;
wherein pressure applied through the one or more bypass ports, when the plug and wiper dart have landed in a landing seat within the wellbore, communicates to the dart nose to cause detachment of the dart nose from the dart body via a release of the attachment device;
wherein a first flow path extends through the plug assembly and the bore of the plug assembly when the wiper dart is not present; and
wherein a second flow path extends through the one or more bypass ports below the dart body, then through the bore of the plug assembly, after a release of the dart nose.
