For an example, smoke oil nipples added after combustion in a muffler, either two-cylinder or four-cylinder two-stroke in acrobatic planes.
They can produce heat of near 325F just above the spark plug in say a DA120 so the exhaust temperature at one from the exhaust is were the smoke nipples are located.
There is enough heat in the exhaust stream to produce excellent smoke clouds while 3D flying at stall to full speeds.
I'm leaning more toward trying the rear of the exhaust cone, it will be cleaner for the plane in the long run.
