This Murphy Rebel is shown with one of our cross over exhaust systems that incorporate two compact mufflers with a pair of cabin heat muffs. The owner chose this system for a variety of reasons. Not only did he want the reduce sound levels, experienced with mufflers, but he also wanted the increased cabin heat. This system gives out 4 times the cabin heat of a standard Murphy Rebel system. This system also helped with diverting the exhaust by the aircrafts float brace wires.
