I want to do a muffler delete on my car.

I want to do a muffler delete on my car. Is it legal to have one suppressing device on my car in the Rutherford county. But if I remove the muffler will the resonator still block some of the loud sound I'm looking for?

My car has 118860 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :

Hello. If you remove the muffler you still will get some sound deadening from the resonator and the catalytic converters. As for the legality of this, that depends on where you live. You need to check with local authorities to make sure. Also keep in mind that removing the muffler can affect the readings from your oxygen sensors. I do not recommend removing it, but instead adding a performance one that creates the sound you are looking for.

Since the muffler only works to limit exhaust noise, your car will still function even if you remove it from your system. Furthermore, a muffler delete won`t affect/damage your engine. More than just improving sound, a muffler delete may boost car performance too.

Deleting these outdated mufflers will improve exhaust flow and reduce engine back-pressure, and, in turn, provide the engine with more horsepower at higher RPMs.

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.

But make no mistake, a muffler delete is illegal in all 50 states, without exceptions. Each state handles muffler laws in their own ways, but every state requires motor vehicles must have a muffler. There`s no getting around it.

It works to quiet down the intense noise created by your engine during combustion. This is a service to the community, preventing loud noises on the streets. However, the muffler does not do anything to raise or lower your car`s gas mileage, so a muffler delete has no impact on gas mileage.

Straight pipes offer better flow than many popular performance mufflers. This can be helpful if you`re trying to maximize performance and fuel mileage. However, high quality performance mufflers such as Paradox Performance Mufflers offer flow just as good -and sometimes better- than straight pipes.

Your stock exhaust system is tuned like a French horn. The length and diameters are designed to reduce pressures every time a pulse of exhaust gas enters the system. A muffler delete adds only about 5-10 horsepower to your car`s engine.

Modern automobile modifiers generally opt for a muffler delete to increase the volume of their vehicle. So if you`re looking for a growling or roaring engine sound, then a muffler delete will achieve this effect.

Benefits of Straight Pipe Systems

Also, with less back pressure, the engine produces more horsepower and torque. Many drivers who race their cars see this as the primary reason to install straight pipes. Your vehicle will accelerate faster and reach higher speeds with a straight pipe system.

Our Turbo Muffler Delete is a sleek single billet design which replaces the restrictive, power-robbing compressor outlet with a smooth, turbulence free air path exiting the turbo. The standard part is located on the outlet of the turbo compressor and is simply designed to reduce engine bay acoustics.

A cold air intake is one of the best options for getting a resonant, deep-sounding exhaust note from your vehicle. When you rev your engine and finally release the throttle, you`ll hear the sound of air flowing through your intake and changing the notes of your engine to a louder, more aggressive sound.

It is true that removing the muffler helps to reduce back pressure and possibly improve the exhaust scavenging characteristics of your system. This does improve airflow, but you won`t feel any noticeable increase in performance.

Reduced Fuel Economy and Higher Emissions

If your car`s exhaust has a leak, this will have an impact on the pressure in the exhaust system, reducing fuel economy and leading to higher emissions.

A straight pipe exhaust system helps your engine run more efficiently. That`s because the backpressure created from the catalytic converter and muffler no longer exists. Less pressure on your engine results in more efficient operations, so you`ll see a slight increase in fuel efficiency.

How long does a muffler last? How many miles it take to replace a muffler? Is theirs any difference between each muffler? (2 muffler)

ANSWER : There is a good chance it is the ’flex’ pipe section leaking. The life of the exhaust depends on mileage, driving conditions, and where you live. Snow and icy climates rip through exhaust systems with rust and road salt.

The 3.0 Hondas come with a stainless steel exhaust system which last for almost forever. The flex pipe typically cracks due to loose engine mounts. If someone has replaced the exhaust, then it may have rusted through. If you have the factory exhaust, then it should last the life of the car unless you live in a snow-type climate. If you want to have the noise looked at, a technician from YourMechanic can come to your home or office to inspect your exhaust system and let you know what adjustments should be done.

My car want start and when it do it shut down and want start until 30 minute or so. Now it want do nothing

ANSWER : When a car turns and won’t start, it is called a "crank no start". When this occurs, the first thing you need to do is see what is missing. All internal combustion motors need spark, fuel, injector pulse and camshaft timing to run. If one of these is missing, you have a crank no start. Diagnose the car and see what is missing.

The GM 3.8l motor has been installed in Buicks, Pontiacs and Chevrolets for decades. Particularly during the 90’s and early 00’s, these motors have used an ignition module with three coils mounted to it. This module is prone to just this type of failure. When it gets too hot, it quits working. When it cools off, it starts again. It can also display intermittent no start conditions. This is a pattern failure on this particular motor. Before I would ever replace the module, I would check for spark and injector pulse. If it just lacks spark, I would check for a crank sensor signal and replace the ignition module.

Before we get too far ahead of ourselves, do a few tests first:

Check fuel pressure. If there is none, check the fuse and the relay.
Check for injector pulse with a noid light. If this is missing, I would suspect a crank sensor. It could be a bad Power Control Module (PCM). (PCM’s are very rare to fail. I have never changed a PCM on one of these cars.)
Check for spark with a spark tester. If it is lacking spark but has injector pulse, suspect the ignition module.

If all these are present, I would take a compression test of all the cylinders. If camshaft timing is off, several of the cylinders will have significantly lower compression. Also, camshaft timing won’t start sometimes then not others; it will either start and run bad or it won’t start at all. It may sound like it is trying to start, but it won’t start.

If all of this sounds to daunting, I recommend booking a car is not starting inspection with YourMechanic

Good luck!

I put the wrong key in my car and a few weeks later my car just shut down and it will not start I believe it’s the computer but…

ANSWER : Hi there. What had happened is the wrong key set the security to the vehicle. This is to prevent the vehicle from starting with the wrong keys. Try removing the battery cables (+) and (-) for 13 minutes. During that time, put the original key in the ignition and turn it on. Activate everything in the car even though there is no power. Then remove the key and hook up the battery cables. The computer should have reset and reset the security. If the security is still being tripped, then I recommend seeking out a professional, such as one from Your Mechanic, to help you

Replaced alternator on car 2 times each time shows it’s charging 14v let car run for a little bit then test drive and car voltage

ANSWER : There are reports that the replacement alternators will not communicate with the engine computer and will not charge correctly. I recommend using only the manufacturer approved replacement part. It can be new or remanufactured but approved for use in the vehicle. Some lower cost alternators on the aftermarket will have charging problems since they will not communicate with the ECM on the vehicle and will stop charging.

What is the best car starter to get for my moms car? (this is her car by The way i just want to get her one for christmas

ANSWER : There are many brands of starters on the market. I would only recommend the dealer starter as the best. You may find aftermarket starters to be rebuilt and the dealer new would be better in most cases. The aftermarket ones may give you lifetime warranties. This does not make them better but a better warranty.

My car will not start Intermittently. I purchased a new battery 2 weeks ago and yesterday the car wouldn’t start. Got a jump and

ANSWER : The issue you are having is probably due to an intermittent fault in the starter motor itself or a deficiency in the starter electrical circuit, for example a large voltage drop due to a poor ground or a high resistance connection. These issues can be readily diagnosed and resolved on a mobile basis if you request a hard starting diagnostic. If you request that diagnostic, the responding certified mechanic will get this resolved for you promptly. Based on Toyota’s Factory Service Manual, the battery should not be disconnected if the vehicle engine is running. The battery acts as a large resistive voltage sink and consequently taking the battery out of the circuit, while the alternator is still running, can create a voltage spike on the car’s electrical system which is not good for voltage sensitive components such as the engine computer. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
