An internist, also called a general internist or doctor of internal medicine, is a medical doctor that specializes in the diagnosis and medical (nonsurgical) treatment of adults.
Exhaust resonators, meanwhile, further reduce the noise by making sound waves that cancel noises out. Structure A typical automotive exhaust resonator is made of a hollow steel cylindrical tube and is attached to the muffler of an exhaust system. This type of resonator is designed similar to that of an acoustic resonator, which creates an âexhaust noteâ that gives the exhaust noise a less annoying and more pleasant tone.
2. Exhaust is louder than normal. Loud exhaust noise is usually the result of an exhaust leak that commonly occurs in the muffler as opposed to the exhaust components located near the engine. As engine exhaust flows through the exhaust system, it is contained and eventually flows through the muffler.
