An exhaust stack system for a muffler having an exhaust stub pipe including a self-holding taper on the outer diameter of the exhaust stub pipe. The exhaust stack pipe also has a self-holding taper on the inner diameter of the proximal end so as to matingly connect to the taper on the exhaust stub pipe. Preferably a securing mechanism holds the exhaust stack pipe in proper orientation with the muffler stub pipe. In a preferred embodiment, the securing mechanism further includes a spring clip member. The exhaust stack pipe has a longitudinal slot approximate the taper and the muffler stub pipe has a hole in alignment with the longitudinal slot so that a hooked end of the spring clip can fit through the longitudinal slot and into the hole. In another embodiment, the securing mechanism is a screw through the exhaust stack pipe and the muffler stub pipe.

An improved pipe-moving apparatus is disclosed having a pipe-insertable elongate member which is articulated for ease of use, particularly for pipe laying near trench ends. In a preferred form, the elongate member has a series of at least two carrier members pivotably interconnected end-to-end, with the proximal end of such series of carrier members attached to the controlling mechanism, and structure supporting the carrier members in alignment when the carrier member series is suspended by its proximal end. A highly preferred embodiment accommodates the removable insertion of one or more additional carrier members in the series to extend the length of the elongate member.
