What is a resonator exhaust?

WHAT DOES A RESONATOR DO? Resonators cancel out a certain range of sound frequencies. You can think of it as a sort of echo chamber for your car's exhaust. Resonators prepare the loud noise coming from your engine for the muffler to silence it. A resonator doesn't just help remove sound, but changes it.

Do I need a resonator on my exhaust?

Do I Need a Resonator on My Exhaust? In most cases, yes. You need a resonator to help control the sounds coming from your vehicle's exhaust system to prevent it from being too loud or obnoxious. Your vehicle will work without a resonator, but you may end up with a check engine light or other issues.

Do resonators reduce sound?

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.

Which is better resonator or muffler?

1. Sound Quality. In terms of sound improvements, if you have to remove one, deleting the muffler is a much better deal than deleting the resonator. Because muffler dampens the sound across RPM, you'll get a louder, raw sound coming out of the engine.

Do resonators make exhaust louder?

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.

Mufflers vs. Resonators

Do exhaust resonators rob horsepower?

While a resonator helps make the work of a muffler easier, thus improving performance and power, it also has some drawbacks. It causes restrictions to the flow of exhaust gases. In so doing, it robs the exhaust of some horsepower and torque. To gain back this horsepower, you can opt to do away with the resonator.

Is it OK to remove 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 a resonator delete illegal?

Generally, resonator delete is not illegal in most places; that means you are at liberty to modify your car's exhaust compartment to your taste. If you choose to remove the muffler and the resonator to make your vehicle sound louder, it is your choice.

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.

Will adding resonators quiet an exhaust?

In addition to quieting the noise coming from your engine overall, an exhaust resonator can also be especially helpful in targeting the most annoying or grating kinds of sounds. A resonator will cancel out frustrating sound frequencies like droning, buzzing, or harsh pitches.

Do resonators restrict airflow?

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.

What does a hot dog exhaust do?

A hot dog muffler is essentially a small bodied straight through muffler. The reason why you will use one is because they are much stronger in construction and more durable. Hotdog mufflers are installed to help to quiten the car. They are particularly used to smoothen the sound coming from the car's exhaust system.

Will removing resonator affect emissions?

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.

Do all cars have resonators?

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.

What makes exhaust raspy?

This is caused by the increased flow of the exhaust gases. A raspy sound may emit from your performance muffler from time to time. It is important to understand how to get rid of this sound to prevent from further problems occurring.

Will a resonator Delete make my car pop?

1. It will change the sound profile of your exhaust. Many vehicles experience a deeper, more authentic sound when equipped with a resonator delete package. Since the main function of this device is purely cosmetic, nothing happens to your vehicle when changing the noise profile.

Can I replace my resonator with a muffler?

Registered. Most people straight pipe it, as you already stated. What you could do is straight pipe the resonator, and then put the aftermarket muffler in place of your muffler delete.

Does flowmaster make resonators?

Flowmaster's universal resonator can be installed in front of or behind the muffler in new or existing installations and will work with other muffler types beyond Flowmaster. These amazing resonators feature full 409S stainless construction and are backed by our limited lifetime warranty.

Does muffler delete add HP?

Pros of Muffler Delete System

It is easy to understand why a muffler delete system can prove beneficial to older cars or old race cars. It not only makes the vehicle sound more muscular, but the horsepower and torque gains at high speed are hard to ignore.

Can you put resonator back on?

Unless you hacked the stock pipes coming out of the resonator there is no reason you can't weld it back onto the pipes. When I replaced my resonator with a Y pipe I left about 6" of pipe coming out of the resonator.

Does straight pipe hurt your engine?

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.

How much does a resonator cost?

The average cost of professional resonator delete is between $100 and $200, if using aftermarket parts. If welding is required, you might need to spend a little more.
