What Is the Purpose of the Exhaust Resonator?
Exhaust resonators are used to create smoother driving conditions, reduce noise from the engine exhaust and enhance engine performance. Exhaust resonators are add-on features within the exhaust system. The resonators are used primarily in combination with the muffler to reduce excessive exhaust noise.
Exhaust resonators create additional sound waves, which effectively cancel out exhaust system noise. The ability of the exhaust resonator to suppress excessive noise helps vehicles pass emission tests. The exhaust resonator stops chassis rattling, which is the primary cause of contaminated fuel emissions. The resonator also helps the vehicle supply more horsepower to the engine without burning excess fuel.
