ABSTRACT:
A vertically-extending L-shaped exhaust pipe and method of manufacturing same are disclosed. The exhaust pipe includes a drain hole located at the bottom of the horizontal portion of the exhaust pipe for allowing liquids to drain from the pipe in order to avoid harming upstream exhaust system or engine components. An elliptically shaped guide is welded into an arcuate slot immediately upstream of the drain hole and is angled in the downstream direction so as to direct the flow of liquid toward the drain opening and away from upstream exhaust system components. The present invention is simple to manufacture, eliminates the need for a noisy flapper lid, and maintains the structural integrity of the exhaust pipe.
