If you are a car enthusiast, I am sure you are familiar with a muffler delete. A muffler delete involves removing a muffler from an exhaust system of a vehicle. It gives your car more power by significantly improving its sound.
The car engine creates combustion in the combustion chamber, which gives your car power to propel its wheels. This combustion is a controlled explosion that produces energy and loud noises in sound waves that pass via exhaust pipe and go out to the environment.
If there is no silencing mechanism, the noise can be pretty loud. Very few people fancy very loud cars, so car manufacturers equip vehicles with mufflers to minimize the noise.
However, car enthusiasts will still want their vehicles to be louder, the reason they go for muffler delete.
So, does a muffler delete void warranty?
Is your car new, still under warranty? But you want to improve its sound?
If muffler delete is something you could consider, read on to determine if it voids your warranty.
What is a Muffler Delete?
Muffler delete is the process in which you remove the muffler at the whole from your vehicle’s exhaust system. You cut off the muffler entirely and replace it with an additional exhaust pipe in this process.
It is an easy process to do, but the cutting of the muffler can be very hard. Thus, if you cannot cut it yourself, look for a car workshop nearby, and they will help you.
Therefore, if you love the loud sound of your machine and want your car to sound better and have more horsepower, get a muffler deleted.
Does a Muffler Delete Void Warranty?
No, a muffler delete will not make your warranty invalid.
Magnuson-Moss Warranty Act protects you from getting denied warranty because of performing any modifications or installing aftermarket parts.
Magnuson-Moss Act is federal law, so it applies to all the states in the USA. It applies to products that cost $20 or more and is not only helpful to cars but also UTVs, boats, motorbikes, and ATVs.
Therefore, if a dealer wants to void your warranty, they must prove if the issue results directly from your car modification.
For instance, if you have done a muffler delete and then soon your headlights fail to function, then your headlights warranty is valid and will still apply.
However, your exhaust pipe warranty will not apply if you do a faulty muffler delete that breaks your exhaust because of rusting.
Well, that is quite a fair deal.
However, sometimes you might lose your warranty even with the Magnuson-Moss act. Most dealers may give you a hard time and even link your problem to the modification.
So if you still want to go ahead with any modification, ensure you only buy the parts from a reputable brand and research extensively what you are going to do and the impacts of the same.
Will A Muffler Delete Pass Inspection?
No! A muffler delete will not pass even the regular inspection of vehicles.
A muffler is a device that suppresses noise, so removing it means that your car will be very loud and sometimes deafening hence the noise pollution.
At the same time, it is essential to note that muffler delete does not increase emission because the muffler does not have any emission equipment.
Is a Muffler Delete Illegal in California?
Yes, muffler delete is illegal in California.
California has strict vehicle laws that do not allow modifications like muffler delete. Also, cutouts, bypass, and whistle tips are all not allowed.
Even though muffler deletes are illegal, you can improve the sound of your car by having specialty performance devices like adjustable mufflers.
Selling and installing any aftermarket exhaust system parts is illegal in California.
However, the modification can be allowed if the sound does not go above 95 decibels or when checked under SAE J1492 and has not compromised with safety laws and other exhaust regulations.
Muffler Delete Alternatives
If you want your car to sound powerful and stuck because you can’t stand the negative impacts of muffler delete, you can still find alternatives.
Fortunately, there are a variety of aftermarket mufflers and exhaust systems that can provide you with a great sound and fantastic flow without dealing with the negatives of muffler delete or a straight pipe exhaust.
Aftermarket companies that will help you get a great sound include; Magnaflow, Paradox Performance Mufflers, Borla, Flowmaster, and Cherry Bomb.
Here are the alternatives to muffler delete;
1. Resonator Exhaust Tip
It is small equipment you attach to the exhaust tailpipe for improving sound.
It is legal, affordable, costs about $30, makes the vehicle exhaust look fantastic, and is very easy to install.
It works magic, and you will notice the change in your car’s sound, and your engine will sound more powerful. However, it will not be as loud as deleting the muffler.
2. Drill holes in the exhaust pipe
Here you drill holes right on the exhaust pipe right before the muffler. It is a cheap and more straightforward method to make your car louder.
It permits sound waves moving in the exhaust pipe to exit before the muffler silences them. The result is a louder and more powerful engine.
It would be best not to drill holes before the catalytic converter because toxic gases and fumes will escape before passing treatment, so you will fail smog inspection.
3. Cold air intake
Cold air intake allows more airflow by sucking cold air instead of the engine bay’s warm air, hence boosting horsepower.
Therefore, when you accelerate a vehicle with cold air intake, it produces a unique sound as the air rushes to the engine. The sound is aggressive, calm, and unique at the same time.
