Narrative:

In the terminal phase of flight at approximately 2;000 ft; I experienced the following: the aircraft yawed to the left engine side with a muffled sound coming from the left engine. Looking at the left engine I noticed what appeared to be red sparks exiting the left engines inboard exhaust stack. The aircraft was set up for landing so I decided to execute a precautionary emergency shutdown of the left engine. I focused on making sure I selected the correct engine and propeller controls so as not to secure the normally functioning engine and declared an emergency. I executed a precautionary emergency engine shut down of the left engine and single engine landing without any further problems.
