Smog has nothing to do with the resonators. They solely have an impact on sound and exhaust pulse tuning.
Normally, altering a part voids its warranty. Your engine warranty cannot be voided by BMW if you install wheels or suspension. However, if you modify those components, they can definitely void your guarantee on your wheels and suspension.

Does a Performance Exhaust Void the Warranty on My BMW?
Although it’s true that aftermarket items, especially performance exhausts, can lead to problems that aren’t covered by warranties, it’s really illegal to void a warranty when someone installs an aftermarket part.
Is Muffler Delete Warranty Null and Void?
You may have heard that removing your car’s muffler can significantly improve its sound. Your car, however, is still under warranty and is somewhat new. Does removing the muffler void the warranty?
Okay, no. The Magnuson-Moss Warranty Act ensures that removing your car’s exhaust system won’t void it. Dealers must demonstrate that the issue is directly related to your modification in order to terminate your warranty. For instance, the guarantee for the light is still in effect if you do a muffler delete and your headlight fails shortly after. However, the guarantee for your exhaust pipe will not be valid if you execute a subpar muffler delete that leads to your exhaust breaking due to rusting.
I believe this to be fair.
Let’s now discuss the warranty act in further detail as well as other issues you should be aware of prior to completing a muffler delete.
Is the warranty voided if the resonator is removed?
I want to make the sound of my sporty Hyundai as sporty as it looks and feels to drive. Will my Hyundai warranty be voided if I remove the resonator from the exhaust system?
Due to the Magnuson-Moss Warranty Act, a resonator deletion won’t technically void your Hyundai warranty. However, if you execute a subpar resonator delete that causes rusting or other harm to your muffler or exhaust system, the modification may void the warranty because the harm was caused directly by the modification. To ensure that the deletion is done properly, speak with the professionals at your neighborhood Hyundai dealer, garage, or muffler shop.
A brief warning
The resonator is legally a part of your emissions system, thus removing it can cause you to fail an emissions inspection even though your warranty will still be valid.
By removing your resonator, you’ll improve the sound of your engine as well as the performance of your sporty Hyundai by reducing the weight of your car. Make sure you have reliable auto insurance in case you struggle to resist the need to test out how your modification impacts the performance of your vehicle.

What renders a BMW warranty void?
I want to change a couple things with my BMW. It is still covered under warranty at the moment, but I don’t want to unintentionally void it by performing any of these changes. Do certain modifications or other actions nullify a BMW warranty?
A modification that results in mistakes or issues with components of the automobile covered by the initial BMW warranty is the only thing that could void the warranty. For instance, if replacing the exhaust system or changing a turbocharger for a supercharger results in the failure of a covered component, the warranty may be nullified.
The guarantee wouldn’t be nullified, though, if you switched to larger wheels or tires, tinted your windows, or covered your taillights in black. The Magnuson-Moss Warranty Act of 1975 provides federal protection for warranties, so as long as you don’t harm other components, you should be fine to go.

Is a BMW warranty void if I have an exhaust?
You run the risk of voiding the warranty on any parts associated with the exhaust system if they are not Dinan or BMW performance accessories. For instance, the warranty would not cover any repairs if the exhaust system you are installing damages your valves internally as a result of improper back flow pressure.
Does removing the resonator harm the engine?
A common auto modification that changes the way exhaust pulses go through the system is the resonator deletion. The resonator component is entirely eliminated during a resonator delete.
A resonator deletion lightens the car and changes the exhaust sound. Usually, it’s a legal alteration that requires little upkeep and doesn’t significantly alter the muffler. However, it may violate the warranty, cause droning noises, limit flow, affect engine efficiency, and turn on the Check Engine Light.
Resonator deletion differs from muffler deletion, which entails removal of the muffler. However, a lot of the advantages and drawbacks of both solutions are similar. Some users also opt to replace the system with a straight pipe exhaust by removing the resonator and muffler.
Does a downpipe nullify a BMW warranty?
Is the BMW warranty voided if an aftermarket downpipe is added? Do you need to tune your vehicle after installing the downpipe?
If you get caught, your warranty may be voided; however, they must show that the item was broken by you. Although a tune is not necessary, doing so will result in a CEL and insufficient use of the DP. However, it is typical practice for BMW to void the warranty for both the attached item and the original item if it is an aftermarket component. Therefore, if your turbo fails, they can simply claim that the DP damaged it.
You can find a ton of information by using the “search” option, which has been discussed a ton.
Although aftermarket equipment does not “invalidate” a car’s full warranty, BMW will reject a warranty claim if they believe the aftermarket part or parts were to blame for the failure or damage.
Due to the increased amount of unburned gasoline in the exhaust caused by the absence of the primary catalytic converter or one with a less dense catalyst, a tune or other add-on may occasionally be necessary to turn off the Check-Engine light (CEL) (“catted” downpipe). A catless downpipe can be used more effectively by tunes than by stock software.
My neighborhood dealer offered me absolute sh*t for the downpipe. claimed that my car was “tagged,” and they won’t fix it even if the issue is unrelated.
Believe it or not, some personnel at BMW dealerships don’t properly comprehend warranty.
They can refuse a work if they think (and can prove) it is due to a specific change you made, but they can’t unilaterally void the entire warranty because of a mod.
I will be really glad if BMWNA does ANYTHING to help postpone the costs of repair if my powertrain fails and they do it. Never expect them to pay for anything; if your downpipe has a tune/flash, there’s no need to install a catless pipe somewhere.
The reason for this is that your car provided data to BMWNA via FASTA, and BMWNA flagged your vehicle. The flag cannot be overridden by another dealer, and they will not be compensated for the repair.
Will removing the resonator turn on the check engine light?
Unless additional significant exhaust modifications are made with it, a resonator removal will not cause the check engine light to come on. This is so that the exhaust system will not be significantly altered when the resonator is removed since it only serves as a sound tuning device.
The check engine light is unaffected by the resonator deletion, an improvement that doesn’t significantly alter the exhaust system. The improvement aids in modifying the pulses that are produced as the car moves through the exhaust system.
Removing the resonator optimizes the pulses generated by your car and boosts power output. The resonator deletion is a terrific technique to enhance the sound of your car while not affecting airflow. It is viewed as a tuning system.
However, when performing a resonator delete, some individuals may also remove an operational component of the exhaust system, such as the exhaust valve. This will make the car’s check light come on.
Resonator deletion may also result in back-pressure variations that could set off the check engine light, depending on the car’s model and the kind of exhaust system your automobile may be using. Between the catalytic converter and the muffler, the resonator is situated. Incorrect resonator deletion could harm the catalytic converter and result in the engine light.
Does a resonator add or subtract HP?
Resonator deletion is not recommended because it may result in your car losing its distinctive tone.
Each type of vehicle has a distinctive sound. The resonance is produced by the resonator.
Your engine’s efficiency may also be affected by a resonator delete. It can result in increased fuel consumption since it influences the back pressure of the exhaust gases.
Even if your goal is to acquire more power, this modification may not be fully safe for your car or truck and may not be worth the risk.
If soot has accumulated and is preventing a smooth flow of air intake, it is preferable to replace the standard resonator with a straight pipe or a new one.
In a word, a performance exhaust system or muffler should be taken into consideration if you desire an audible engine sound.
A resonator deletion should not be an option, though, if you like a quiet, smooth, and lighter vehicle.
Whatever you choose, unless you update your exhaust system, the horsepower improvement will remain modest.
