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.
Much like a muffler, a resonator is dimensioned to reduce the noise from the engine as the exhaust gases pass through its chambers. Adding a resonator to your existing exhaust system can not only give your car a sporty sound, but it can reduce the raspy sound of the exhaust as well.
