How much does it cost to replace an exhaust system

If you’re having a problem with your exhaust system and you wanna know how much does it cost to replace an exhaust system, then you’ve come to the right place. The performance and aesthetics of a car are significantly influenced by the exhaust system. On a busy street, nobody likes a smoke machine that is sputtering. More importantly, once the leaks get inside the car, they can be fatal. Before we continue on discussing rusted components and odd odors, it’s important to note that there are other reasons to consider replacement prices besides a broken exhaust system.

To improve your car, you can get rid of the factory-installed system and replace it with a tailored fit. Thus, in this article, we’ll be discussing the topic  “How much does it cost to replace an exhaust system”. So, let’s begin!

How much does it cost to replace an exhaust system?

Depending on the style, size, and individual components of the exhaust system, the price of an exhaust system can range from $300 to $1200. However, this will depend on your vehicle and the garage you choose. This is for the labor and the associated parts. Fortunately, it is uncommon for an exhaust system to need to be replaced entirely at once; rather, the parts after the catalytic converter are typically the most vulnerable to rust and damage.

Parts that make up the exhaust and how much does it cost to replace them

Exhaust manifold?

A manifold is a component that joins different pipelines for gases and liquids. The exhaust manifold in this instance fastens to the side of the engine and directs the exhaust fumes from every cylinder into a single pipe. Due to the fact that it almost invariably goes directly from the side of the engine to the underside of the automobile, this pipe is frequently referred to as the “down-pipe.”

Because the manifold is bolted to the engine, a number of parts frequently need to be removed in order to check or repair it. If the original manifold is leaking, a replacement would be relatively expensive because they are a complicated and infrequently replaced part.

The manifold gasket, which seals the gap between the manifold and the engine block, is another component that can break and needs to be replaced. Although the part is inexpensive, changing it may take a few hours.

Depending on the car, it may be possible to reasonably repair leaks at the bottom of the manifold between it and the Flexi, cat, or mid-pipe. Due to the difficulty of the task, you should budget between $350 and $1,000 to replace the exhaust manifold. Cast iron or stainless steel can be used to make exhaust manifolds, which has an impact on cost as well.


Everything from the catalytic converter outlet to the exhaust tips is part of the cat-back exhaust system. A sizable pipe often connects the converter to the muffler in exhaust systems. Additionally, a resonator that reduces some of the exhaust sounds can be fitted before the muffler.

Different bends are added to a performance cat-back exhaust to lessen back pressure. You may pay $250 to $2,000 to replace this, depending on the style of exhaust you desire.

The most popular sort of exhaust replacement is a cat-back system upgrade since it provides nearly a brand-new exhaust system without having to replace pricey components like the catalytic converter or exhaust manifold.

Catalytic Converter

The catalytic converter is now commonly integrated into the downpipe, or at the very least the front piece of the exhaust, which runs under the engine. A secondary cat is also present in some autos, located midway in the middle. materials like platinum and palladium found in the catalytic converter react with exhaust gases to eliminate some of the hazardous components.

Catalytic converters, sometimes known as “cats,” are expensive to produce and must consequently be replaced since they include exotic materials that reduce harmful emissions. Sadly, this has resulted in a pattern of them being stolen from specific automobiles. A general off-the-shelf device will cost less than an OEM (Original Equipment Manufacturer) cat, but installing the latter will require some fabrication as opposed to simple bolting in.

One of the more pricey components to replace is the catalytic converter. It often costs $300 to $2,000 or more. Usually, the high cost is caused by the material rather than the work. This component is pricey since it requires precious metals for the chemical processes.


The noise originating from the engine is muffled by the vehicle’s muffler. It also induces back pressure to enhance performance. The average cost to replace a muffler is between $100 and $300. Performance mufflers, however, can cost significantly more since they boost engine backpressure and provide better sound.

Cost of Replacing the Full Exhaust System

You’re going to easily spend $1,000 or more to replace the exhaust in its whole. While some people choose to spread out the cost and work on the exhaust gradually, others decide to do it all at once. Even if you want to improve performance or sound, the exhaust system on most cars can usually be repaired or upgraded. In many instances, you can get the desired result by replacing just a few crucial components. The replacement of the cat-back is far more frequent than that of the entire exhaust system.

Factors affecting the cost of an exhaust replacement

Below shows the cost of replacing an exhaust;

Cost of Parts

Older models have cheaper solutions available, but luxury vehicles will require pricey replacement parts. High-performance mufflers, for instance, start at $75. Depending on the thickness and caliber of the material, it may cost $300 or more. Similarly to that, the average cost of an exhaust tip ranges from $25 to $150. The majority of auto exhaust systems have tips already attached.

Styles and Material

The two popular forms are cat-back and axle-back. Additionally, there are more expensive high-performance variations available. Metals like steel or aluminum are frequently used. Mild steel is a cost-effective option, although it rusts quickly. Aluminum that has been galvanized is less noisy and more resistant to corrosion. However, stainless steel is more expensive and more durable.

Labor costs

It doesn’t take much effort to replace your car’s entire exhaust system. You can replace it yourself if you have the necessary equipment, clear instructions, and some experience. Having said that, don’t take a chance if you’re unsure of your technical ability. The better choice is to leave your car at the shop for a few hours.

It won’t take more than a half-day to replace a car’s exhaust system, and labor will typically cost you $50 to $60 per hour. It also depends on whether you are changing the entire system or just a few components. If the latter, the type and quantity of parts that need to be replaced will determine the overall time required.

It’s possible that the dealership where you bought the equipment will replace it without charging you more. Customized items, however, could push up the price.

How do you know if your exhaust needs replacing?

Given the variety of components in your exhaust system, there are a few potential indications that one or more of them—or your entire exhaust system—may be defective. The following are some of the most typical indications that your exhaust needs to be replaced:

  • Exhaust leaks can raise engine temperature and lower efficiency, which results in higher fuel consumption.
  • When driving, problems with your catalytic converter may cause you to accelerate less quickly.
  • Parts that hiss, roar, or rattle may be due to leakage or lose components.
  • An exhaust pipe that is rusted out can generate vibrations.
  • Hot gases from leaks in your exhaust system can cause the engine to overheat, melt plastic components, and emit an offensive burning odor.
  • Leaks in your exhaust system are the source of the gas smell.
  • As soon as possible once your check engine light comes on, go to a garage.

How important is it to fix your exhaust system?

  • At best, the engine performance will be impacted by the exhaust issue, frequently leading to increased fuel consumption and decreased power output. Future repair costs could be significantly higher if specific sections aren’t fixed right away.
  • The safety of you and your passengers should be your top priority when having your exhaust repaired. To keep fumes away from passengers, exhaust systems exit at the rear of the vehicle. However, leaks from any of the exhaust joints or components can readily let toxic gases into the cabin.
  • Furthermore, you might not be able to notice the fumes coming in because you can get used to the smell over time.
  • Headaches, illness, and weariness can result from breathing in exhaust fumes. All of them are not recommended when operating a vehicle.


In conclusion, the price to replace an exhaust system varies significantly based on the type of exhaust components required, the make and model of the vehicle, and whether OEM (original equipment manufacturer) or aftermarket parts are chosen. Simple exhaust system changes can cost as little as a few hundred dollars, but the price can rise to several thousand dollars for more complicated systems or high-performance exhaust changes. The final cost also includes a sizeable portion of labor expenditures, which can vary depending on the region and the mechanic’s rates.
