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.
In many cases, resonators are added in addition to mufflers to luxury cars as a way to make the car quieter overall. Sports compact enthusiasts are keen to perform exhaust repair on their vehicles to increase horsepower and to make even the most mild-mannered Honda Civic sound like a full-on sports car.
