Thread: Rules about flying over residential areas?

  1. #21


    Most single engine exhaust systems are designed to effectively as possible remove exhaust and heat from the individual cylinders.
    They are an air cooled engine, so a whole different animal than an automobile.
    So, the muffler is not built to reduce noise. Doing so hinders its ability to do those first 2 things we talked about.
    The sad part for an owner is, a new system for these aircraft can cost anywhere between $2,000 to $9,000 .
    So none of us are laughing to hard when we have to write that check Lol
