Narrative:
On feb/thu/97 at approximately XG30 pm, I took off from stuart airport in florida to travel to nassau, VFR. I had done a thorough preflight and runup before takeoff with all indications of a normal flight. I use noise-canceling headsets and have attuned myself to the normal sounds of my engine when I am wearing them. My takeoff was normal until I reached 300-400 ft AGL when my engine started missing. I did my normal routine for a rough-sounding engine (that I learned as a student) but the engine continued to miss. My passenger could also hear the change in the sound of the engine. My other indicators were normal (oil pressure, temperature etc). I asked stuart tower if I could make an emergency landing, which I did without incident. A local repair station checked out the plane and found a broken baffle in the muffler which had blocked 3/4 of the exhaust. They replaced the muffler.
