Default Black soot in tail pipes

When we were installing the SLP Cat Back, I noticed that the old tail pipes we pretty black. Is this normal? I have been running a C&L MAF Kit, so I would have expected to not be running rich. However, the car has 45k miles on it with only a few grand on the C&L.

Also, at idle, my rpms cycle from about 600 to 1200. The car wants to run around 600 but then starts to bog down and then they shoot up to 1200. Sometimes this happens more often then others.

Any ideas?
