A resonator makes your overall exhaust note louder and more aggressive. It's not quite a straight-pipe, but it isn’t too far off. Resonators also have less baffling and don't reroute exhaust gases as much as a muffler. This reduces back pressure, potentially freeing up a few horsepower.
Is a resonator better than a muffler?
While mufflers reduce the exhaust volume, resonators tune the exhaust for a more pleasant sound. Resonators will remove some of the raspy and high-pitched noises from the exhaust but won't do anything to muffle the volume.
Do resonators reduce noise?
The resonator is a complement to the muffler in that it removes high-pitched noises along with annoying hums and buzzes. It creates a smoother exhaust note, but doesn't affect volume. The resonator is designed to eliminate sounds at a particular frequency which bounce off the inside of the device canceling each other.
Do resonators count as mufflers?
Resonators do count as mufflers. It's not like you would be running open headers, you have some form of sound control in the exhaust.
Related Question Are resonators louder than mufflers?
Will removing resonator affect performance?
When you take out the exhaust resonator and replace it with a pipe, the back pressure can be affected. It will reduce the efficiency of your car and you might end up consuming more fuel while also hearing a louder noise. Consequently, this leads to achieving peak performance and saving fuel.
Will a resonator delete cause check engine light?
No, that won't cause a CEL. It's when people cut out/remove the active exhaust valves that they get CELs, so as long as you don't mess with those then you'll be fine.
What is the use of resonator?
Resonators are used to either generate waves of specific frequencies or to select specific frequencies from a signal. Musical instruments use acoustic resonators that produce sound waves of specific tones.
