Exhaust resonators provide a wide array of benefits to vehicle owners. Aside from reducing the noise from the engine’s exhaust system, resonators also enhance overall engine performance and smoother driving because more horsepower is yielded without wasting as much fuel. To provide the sound the maker of the car wants as well as helping performance in a specific RPM range. Extra few bucks to replace the resonator, it is. Skipping it can really screw up the way your engine is tuned.
The resonator is designed to work best in the frequency range where the engine makes the most noise; but even if the frequency is not exactly what the resonator was tuned for, it will still produce some destructive interference. This device works just like the resonator chamber in the muffler -- the dimensions are calculated so that the waves reflected by the resonator help cancel out certain frequencies of sound in the exhaust. Report Abuse. The resonator is used to provide the sound the maker of the car wants as well as helping performance in a specific RPM range. So by removing it, you may get the sound you want at the expense of performance. The exhaust system on a car can be tuned just like the pipes of a organ. It has to do with resonance, volume and length. It is one of many details that auto engineers make big bucks figuring out. I like loud. Anyways there is a long resonator right after my catalytic converter. My friend says it's for both noise and emission... show more I'm redoing my exhaust system for my 1996 Mazda MX-6. I just want to make it a straight pipe with a glass pack (to tone it) instead of muffler to make it sound loud. Advantages. Exhaust resonators provide a wide array of benefits to vehicle owners. Aside from reducing the noise from the engine’s exhaust system, resonators also enhance overall engine performance and smoother driving because more horsepower is yielded without wasting as much fuel. This type of resonator is designed similar to that of an acoustic resonator, which creates an “exhaust note” that gives the exhaust noise a less annoying and more pleasant tone. My car is a vr and I have my resonator removed. My best example of a removed resonator is if it were posible to turn up the exhaust note like volume on a stereo. What I mean is my vr sound the same eccept you don't have to struggle trying to hear it. Aight just wondering what the heck a resonator does... I know something with sound but I dont know.. I just got a vr6 exhaust from a friend. I got the exhaust and the resonator. It is engine RPM which causes exhaust gas pulses at a certain frequency, exhaust gas flow speed, size of the exhaust pipe and length of the exhaust pipe etc etc etc. . . . . If the right conditions occur so does resonance and the sound booms. So the purpose of the resonator is to prevent resonance from happening. Specically, the resonator does this by momentarily storing exhaust pressure in the exhaust pipe. This occurs when a pressure pulse moves down the pipe. During the lull period before the next pressure pulse this pressure gets released rapidly.  The Resonator. When a wave hits the hole, part of it continues into the chamber and part of it is reflected. The wave travels through the chamber, hits the back wall of the muffler and bounces back out of the hole. This device works just like the resonator chamber in the muffler -- the dimensions are calculated so that the waves reflected by the resonator help cancel out certain frequencies of sound in the exhaust. Central Texas. Nope, a real resonator is a glass pack or small muffler looking thing, designed to mellow out the tone of your exhaust. Used in conjunction with your catalytic converter (emissions) and your muffler (self explainatory), the resonator attempts to break up the sound of each combustion into more of a hum. If you put your lips together and blow, out comes THBBBBBBT!.. Do the same thing to a horn, and you get a pleasant, solid tone instead What exactly is a resonator? The resonator is part of your exhaust system, but it is not the muffler. It is sometimes known as a pre-muffler because it is installed in the exhaust system after the catalytic converter and before the muffler. Some cars and trucks have them, others don’t. If your resonator has rusted out, or you're repairing your exhaust system and wondering if it's worth the extra few bucks to replace the resonator, it is. Skipping it can really screw up the way your engine is tuned. 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 “exhaust note” that gives the exhaust noise a less annoying and more pleasant tone. The sound can be enhanced by means of adjusting the exhaust note
