A muffler is a vital component of the car exhaust system responsible for dampening vehicle emissions and internal combustion engine noise. Having your muffler in good condition will enhance environmental safety by reducing the neighborhood’s carbon monoxide pollution and noise.

Luckily, you may choose to weld your muffler or just clamp it. But many people will prefer the former. Why? It’s a more durable choice that will 100% address the emission issue. Read on to learn how much to weld an exhaust.

How Much Does Professional Muffler Welding Cost?

Welding a muffler can range from an easy skill to a complex job that may require an expert. And since we don’t regularly weld mufflers, it’s hard for many car owners to know the actual welding cost.

A minor muffler welding can cost you from $30 to $500. However, the average professional muffler welding cost is around $280. Sometimes, the costs can go up to $750, especially if you are welding a new muffler. And if other exhaust system parts are faulty, you can pay a total of $1000 to $2500 to repair the whole system and get back on the road.

Below is a table with an exhaust pipe welding cost overview.

  • Minor welding – $30 – $500
  • Average Minor welding costs – Around $280
  • Welding new muffler – $75 to $750
  • Welding muffler with other exhaust components – $1000 to $ 2500

Note that the weld exhaust pipe cost may include the tools like welding rod, the energy charges, and other items needed. However, the actual labor costs may be included in the above charges or added as extra charges.

Same case with the muffler cost if you choose to purchase a new one. The labor cost range from $80 to $100. But before we close the heading; how much for a new muffler? It ranges from $100 to $300.

Why Do You Need to Weld a Muffler?

You now know the average costs of welding a muffler. But why would you weld your muffler? The first reason is to attach the new muffler to the system. Many people opt for welding because it’s more firm and more durable than clamping. Secondly, your muffler may have a hole that causes the gas leak or excessive noise. And apparently, welding an existing muffler is cheaper than replacing it only if it has fewer damages.

Where Can You Get Your Car Exhaust Welded?

Visiting an automotive technician is recommended to give you good advice based on your muffler condition. You may also visit exhaust system experts or a muffler shop. Note that the welding process may be complex, and an unknowledgeable person can even damage it further by making unwanted holes. Simply, search for muffler welding near me, and you will get welder muffler experts.

Factors Affecting the Cost of Welding a Muffler

Although we have discussed the average costs above, several factors can determine how much to weld exhaust pipe. See below:

– Muffler Size

You cannot compare the mufflers in trucks and those in small cars. Usually, trucks have larger mufflers than small cars. So, the cost of welding a larger muffler will be higher than a small one.

– Welder’s Experience

Experienced welders are confident in what they do. So, they will charge more compared to a novice. But working with an experienced welder is better because you avoid damage risks which can cost you even more than the average.

– The Condition of the Muffler

Mufflers with significant damages will need more time to fix. As such, the welder may charge more for labor and other materials they may use.

– Muffler Type

Different car manufacturers have unique muffler designs. Some automakers may have complexly designed mufflers that may require more time to weld. In this situation, the welder may charge more than less complex designs.

– The Location of the Muffler

A muffler located in a harder-to-access area, like under the rear bumper, can cost more to weld. This is because the welder may take more time to remove the bumper to access it.

Signs That Indicate Your Muffler Has Issues

A muffler, being a component under the vehicle, tends to be ignored much. That’s the reason you’d not notice the muffler issue fast. Here are the signs to determine if your muffler is damaged:

– It’s Louder Than Usual

Any louder than the ordinary noise from the exhaust pipe means that the muffler has a problem. Also, the noise may be a result of a broken exhaust pipe.

– Reduced Fuel Efficiency

A damaged muffler will affect the exhaust sensors that aid fuel injection. This can result in poor gas mileage because the electronic control module will have inaccurate emission readings.

– Condensation in the Exhaust Pipes

Condensation happens when air moisture meets gases from the exhaust system. And if the muffler is damaged, it will never control the condensation, so the water will be dripping from the tail pipe.

– Bad Smell

The muffler works with other components like the catalytic converter to reduce harmful gases expelled through the tail pipe. If the gases are filtered before the process happens, you may smell a bad odor when the engine runs.

Different Types of Mufflers

There are various mufflers depending on their vehicle mode and the manufacturer. Surprisingly, you may learn their welding costs are different, as we discussed earlier. Here is the list of mufflers you will find in the market:

– Resonance Type Muffler

It comprises tuned pipes to absorb, cancel, and redirects the sound waves out. It’s very effective in reducing low-pitch tones.

– Absorber Type Muffler

The most popular because it absorbs both high and low-frequency sounds. The muffler has two chambers, one with perforated tubes and fiberglass that absorbs the noise. Afterward, the gases enter the second chamber and leave the system.

– Wave Cancellation Type Muffler

Its design elements create counter waves to eliminate some frequencies. These mufflers give the vehicle an improved exhaust tone.

– Combined Resonance and Absorber Type Muffler

It’s like the standard straight-through muffler, but you will note it has a resonator in the middle. It’s packed with effective sound-absorbing materials

– Baffle Type Muffler

It’s the simplest muffler on the market, but that doesn’t mean it cannot handle the car’s horsepower. It has numerous tubes with holes and some chambers that create resistance and turbulence.

How Can I Fix My Exhaust Without Welding?

Many car owners who fix minor muffler issues at home use aluminum sheets to cover the holes. Then, they can use clamps to attach them firmly, and the noise or leakages reduce. Also, you can bold it to the vehicle underbody if fixing a new exhaust.

Does Car Insurance Cover the Cost to Weld a Muffler?

Typically, ordinary insurance does not cover exhaust welding costs. But if you have comprehensive coverage, the insurance may cover the welding costs.

Frequently Asked Questions (FAQs):

What Does a Hole in The Exhaust Sound Like?

The first annoying thing with a hole in the exhaust system is the excessive noise and leaking of smelly gases. Note that the size of the hole determines the noise.

So, the bigger the hole, the louder the noise. You may also experience poor gas mileage and loss of power, especially when climbing hills.

Does A Broken Exhaust Affect Acceleration?

Yes. A broken exhaust will affect the acceleration. Usually, when the exhaust leaks, it reduces the back pressure, thus reducing the overall engine power.

This results in slow acceleration and poor gas mileage. In simple, the vehicle won’t handle the loads, and also, in hilly places, it will perform very poorly.

Is It Better to Weld or Clamp Exhaust?

Welding or clamping the exhaust are effective. However, both have pros and cons, so it’s hard to say which is better. Below are the comparisons:

Welding offers a permanent solution that will last longer than clamping. Clamping offers the best temporary fix, especially if you plan to replace the exhaust soon.

You can easily do clamping at home, but welding requires a professional. Also, if you decide to replace the exhaust, it will be easier to detach a clamped one than the welded one.

Additionally, the cost to weld exhaust leak is usually higher than clamping due to power charges.

Can You Drive a Car with A Hole in The Exhaust?

Driving with a hole in the exhaust system is possible but has some disadvantages. First, the exhaust will be noisy, and you will disturb the neighborhood. This can result in charges for noise pollution.

Secondly, the exhaust will leak harmful gases into the environment, and you will get fined. Third, the vehicle will consume more fuel and reduce engine power.

How Long Does It Take to Weld Exhaust Pipe?

The duration to weld the exhaust pipe depends on the level of damage it has. Note that the weld has to dry after welding, which can take around two to four hours. You can estimate it to be around three to five hours on average.


The cost of welding a muffler is determined by many factors. First, you need to check the level of damage on the muffler. Second, you can consider the type of muffler your car has as well as its location. So, prepare to pay dozens or even hundreds of dollars. But note that welding is more durable, thus worth the cost.
