  And motorcycles with defective mufflers should be banned. Airplanes are already heavily restricted in where they can fly.

    Motorcycles with defective (or removed) mufflers are banned in most places. Airplanes with defective mufflers should be banned too.

      Because of the strict maintenance requirements on certified aircraft, you won't find many (read: basically zero) piston engine airplanes flying with improperly modified or defective mufflers. In single-engine airplanes, those could represent a significant safety hazard to the people in the cabin. Turboprops and jet engines don't really have mufflers per-se. Some aircraft have aftermarket "hush kits", but that's relatively uncommon as well.

        The one and only piston-powered airplane I've taken into a deep pre-buy inspection had a wrecked muffler core. My sample size is one, so did I "win" the lottery? I have no particular reason to believe this aircraft is especially noteworthy for its airworthiness or level of care.
