The encased exhaust is a traditional aftermarket expansion chamber muffler system for a two stroke engine encompassing a duct fan/propeller. The propeller is mounted directly to the engine's driveshaft, eliminating reduction gears and belts allowing for more airflow and less weight. This eliminates the muffler and replaces the cage on a paramotor, allowing for more airflow through the funneled air duct. The configuration of these two functions exists in a particular sequence.
