Abstract: A pipe accessory mounting apparatus for removable engagement with a substantially horizontally-oriented pipe provides, in at least one embodiment, a display wall and a heat wall substantially linearly aligned with and spaced apart from the display wall. The heat wall is configured for being selectively positioned a distance behind an end of the pipe, in a position between the pipe end and the display wall. An at least one elongate support arm is engaged proximally with each of the heat wall and display wall and configured for being removably secured distally against an outer wall of the pipe. A front surface of the display wall is configured for providing a visual display. During use, where the apparatus is engaged with an exhaust pipe, for example, the heat wall is capable of absorbing and deflecting any hot air emitted from the pipe end, allowing the display to remain substantially unaffected.
