There is a very distinct difference between natural gas and sewer gas smells. Sewer gas is pugnant and sort of rotten egg smell where natural gas is very sharp and distinctive. Turn on a gas burner w/o lighting it to become familiar with its smell.
About the extra pipe, it may be an old abandoned natural gas pipe which used to go under the house foundation and was later replaced going through the wall. i am sure it is not a sewer vent pipe.
