A resonator installed as part of your car or truck's exhaust system serves one main purpose — to resonate. It's sort of an echo chamber for your car's exhaust, preparing all of the loud noise coming from your engine for the muffler to silence it.

Also question is, will removing resonator affect performance?

Because the resonator delete is part of the back end of the exhaust system, removing the device can sometimes impact the performance of your catalytic converter. When that occurs, you can sometimes trigger a check engine light warning or a code in your system because there are back pressure changes which occur.

Furthermore, do I need a resonator on my car? If you want your car to be a little louder, then I would recommend leaving the resonator on, but if you want the car to be a lot louder and don't care about fuel efficiency, you can remove it completely. The other option is taking the middle ground of changing the muffler and or the resonator.

Also to know is, does removing resonator increase horsepower?

The resonator does restrict exhaust flow and rob some horsepower. If you remove the resonator and all the rest of the exhaust system such as the muffler then there may be a slight increase in horsepower.

Where is the resonator located on a car?

The resonator on a car is a hollow chamber in the exhaust tract. Its location is placed a certain distance from the muffler and engine to allow the resonant effect.

What happens if I take off my resonator?

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.

Is resonator delete good or bad?

In this case, a "resonator delete kit" is an ideal upgrade. 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.

What does a bad resonator sound like?

Excessive noise: A damaged or failed resonator can result in unwanted noise coming from the vehicle's exhaust. Typically, the sound is described as a high-frequency buzzing. 5. Unusual smell: A leaking resonator can allow noxious fumes to escape from the vehicle's exhaust.

Will a resonator Delete make my car louder?

The resonator delete will alter the sound but the sound produced might not be satisfactory. If you are looking for something louder and more powerful, you'll want to go with the muffler delete. At the same time, this is going to help you reduce your vehicle's weight significantly. That can provide even more benefits.

What is the purpose of a resonator delete?


Function of a Resonator
It's sort of an echo chamber for your car's exhaust, preparing all of the loud noise coming from your engine for the muffler to silence it. But there is far more science to it than that. The resonator doesn't just remove sound, it changes it.

Does a resonator reduce noise?

But as opposed to a muffler, a resonator simply TUNES the EXHAUST. It does not necessarily reduce sound and though some do to a much lesser extent than mufflers. On occasion, when installing a new Legato Performance Exhaust system, owners will remove the resonators thinking that it will increase flow and improve sound.

Is intake resonator necessary?

An air intake resonator is a crucial component to an automobile engine's intake system. It allows the engine to run more quietly as well as more efficiently. An air intake resonator is a crucial component to an automobile engine's intake system. It allows the engine to run more quietly as well as more efficiently.

Will removing resonator void warranty?

Registered. No the modification does not void the warranty. If you modify the exhaust by removing the resonator and then the muffler cracks, or a hanger breaks off, they can not void the warranty, and if they try, they need to prove that the damage resulted because you removed the resonator.

Is it legal to remove resonator?

You can remove the resonators and mufflers and still be legal. If you have the PE, a muffler delete will throw codes and send the car into semi limp mode.

Do resonators restrict airflow?


A resonator will not restrict air flow that much, but it will change your exhaust tone significantly. If it is a point that it is almost too loud, it is not a bad idea.

Can you pass emissions with no resonator?

You will have no problems passing an emission test with the resonator removed. You don't put on a Flowmaster muffler and leave the resonator, it completely defeats the purpose of the Flowmaster.

How much HP does a muffler delete add?

So for most cars, the muffler delete will not add any power. Some cars will gain some power, but generally it's not much, usually under 5 horsepower. However, if you have a car modified for more power, and still has the stock mufflers, then you'll have more gain.

What is inside of a resonator?

The resonator contains a specific volume of air and has a specific length that is calculated to produce a wave that cancels out a certain frequency of sound.

Does straight piping increase HP?

The biggest reason that many people opt for a straight pipe exhaust is that these systems enhance your car's horsepower. You get better fuel economy and slightly better horsepower. However, the size of the pipe is important. You can't just go and get a thick pipe for your car.

Do resonators reduce drone?


Without really affecting the overall volume or exhaust note, a well-placed resonator can eliminate the drone that we all know and can't stand. Resonators complement mufflers by reducing annoying drone and providing a smoother exhaust note. Resonators are designed to eliminate a sound wave at a given frequency.

Does cat delete increase HP?

Increased Horsepower
Cars that have their catalytic converters removed experience an increase in engine horsepower. Removal of catalytic converters from cars allows exhaust gases to exit their engines much faster and at higher levels.

Does straight pipe hurt your engine?

a race car style exhaust system is a bad upgrade for a street vehicle. A straight pipe, for example, can cause exhaust gas velocity to increase. This will likely reduce engine performance below 2,000 or 2,500 RPM, making your vehicle a little slower to launch from a stoplight.
