If you have a sporty compact car and installed an aftermarket exhaust system, it is probably equipped with an exhaust resonator. The internal components of an engine can make a variety of different noise frequencies during operation and these frequencies change as the engine speeds up or slows down. Exhaust resonators are devices that are built into or added to the exhaust system. To help cancel out most of the frequencies of the engine internals during the range of operation at which the engine is loudest. 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. There are a variety of aftermarkert Honda Civic Exhaust packages available, but unfortunately what many enthusiasts will find if they simply install the exhaust is that they will hear excessive exhaust noise or “exhaust buzz”. This raspy sounding exhaust noise can be due to a couple different things: a leak in the exhaust system, rattling exhaust pipes, or ill-tuned muffler placement. Luckily, installing an exhaust resonator can assist in reducing the rasp. 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. It is important to note that some states have laws against modifying your exhaust system in any way, so before you add a resonator, you should check with the proper authorities on your state’s emissions laws.
