A muffler is an important component of an engine's exhaust system. The muffler is found near the back of a vehicle, and its purpose is to reduce the noise produced from the exhaust process.
When the muffler is damaged or has a hole in it, this causes the pre-muffled exhaust to leak, increasing the sound that comes out of the exhaust system. Although it is possible that exhaust leaks can occur before the muffler, in most cases, loud exhaust is caused by a leak in the muffler itself.
