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.
Piping is 2.5in inlet from the cat to two 2.25in outlets. It has a nice deep throaty sound, pretty loud if I'm driving hard but fairly quiet under 3k rpm and it doesn't drone. Good mid-range torque response. Just some comments on a few of the exhaust that you mentioned from what I've seen on my friends cars though. The HKS hipower resonator hangs kinda low, apexi dual N1 looks nice and pretty quiet, BC spec2 is deafeningly loud...love it.
