The pipe of the flexible pipe assembly includes a first end portion that is coupled to an external vertical exhaust pipe that allows exhaust to escape from a truck and a second end portion that is coupled to a pipe to an outlet of an exhaust aftertreatment system (EAS). The pipe also includes a third portion, which is a bellows, coupling the first end portion to the second end portion of the pipe of the flexible pipe assembly. The first and second connection assemblies couple the sleeve to the pipe of the flexible pipe assembly by passing through holes in the sleeve and the pipe of the flexible pipe assembly.
