I recently noticed that when I warm up the car in the morning, if your looking at the rear of the car, that the Left Exhaust emits more emissions gases than the right. I know this because on a cold day you can see the exhaust BREATH coming out of both, but more so on the left side.

Does anyone know why?

The vapor is water, which is from condensed steam as it is cooled. The left side of the exhaust is longer, and probably cools the exhaust more as it is traveling out, providing more of the visually evident exhaust.

Wait souldn't it be, if it's cooler than less is visable since it's closer to ambient temp outside?

No, the cooler it gets, the more water it will condense, which will in turn be more visible.

It's normal.
