Abstract: A removable exhaust pipe cover for placement over an exhaust pipe opening of a non-running internal combustion engine for excluding water and debris from entering the pipe. The cover is an elongated tubular member of water repellant material which is preferably flexible to a degree, the flexibility being for allowing constricting and sealing against the pipe when in use, and for compact folded or collapsed storage of the cover when not in use. The tubular cover has a closed top end, an oppositely disposed open bottom end, and an annular sidewall extending between the two ends. The bottom open end of the cover, in at least one embodiment, has a elasticized gathered hem which holds the cover tightly closed about the exhaust pipe with the closed top end and upper portion of the sidewall covering and thus closing the open end of the pipe when installed.
