摘要：
A device and method for muffling the sound from an internal combustion engine is described, wherein the device is a tube made of a suitable material such as rubber and is attached to the exhaust outlet of the vehicle. Further described is a method of muffling the sound of an internal combustion engine that is comprised of taking a length of tubing, having two ends and attaching one end of said tubing to the outlet of the exhaust of an internal combustion engine, and directing the other end of said tubing toward the ground surface, by forming an approximate ninety degree bend, such that this second end of the tubing is in close proximity with the ground surface, with the result that the sound level of the exhaust from the engine is substantially reduced.
