What Determines the Cost to Replace Entire Exhaust System?

Type of vehicle: An essential factor determining the cost of replacing your exhaust system is the type of vehicle you have. If you own a smaller car, the replacement might only cost a few hundred dollars.

On the other hand, if you have a larger SUV or truck, the replacement could cost over a thousand dollars. The type of vehicle you have will also affect the labor required to replace the exhaust system.

In general, it takes less time to replace the exhaust system on a smaller car than it does on a larger vehicle. This means that the labor costs will be lower for a smaller car.

Type of Exhaust System: When shopping for a new exhaust system for your car, you will have two options, OEM- or aftermarket exhaust system.

OEM stands for Original Equipment Manufacturer. These are exhaust systems that are made by the same company that manufactured your car.

Aftermarket products are made by companies other than those that made your car. In general, OEM parts are more expensive than aftermarket parts.

However, they usually last longer and may fit your vehicle better than aftermarket products. When deciding between OEM and aftermarket parts, it is essential to consider the product’s cost and quality.

Different Types of Exhaust Systems

If you consider choosing an aftermarket exhaust system, here are some different types you could choose from:

Cat-back system: This is the most common type of aftermarket exhaust system. As you might tell from the name, it includes exhaust pipes, muffler, and all other parts after the catalytic converter.

Axle-back system: This system includes the parts after the rear axle and usually consists of the muffler, tailpipe, and tips.

High-performance system: This system usually includes everything from the exhaust manifold to the tailpipes. Its purpose is to increase the exhaust airflow and improve the performance of your car.

What Is Included in a Full Exhaust System?

A complete exhaust system includes the manifold, exhaust pipes, catalytic converter, oxygen sensor, muffler, and tailpipe. The entire system is responsible for routing fumes away from the engine and out of the car. However, the exhaust manifold is usually not replaced.

Manifold: The manifold is the first component of the exhaust system. It’s a cast-iron or stainless steel piece connecting to the cylinder head’s engine. The manifold has ports that correspond to the cylinder head’s exhaust ports.

Exhaust Pipes: The exhaust pipes are the metal tubes connecting the different parts of the exhaust system. The size of the pipes will vary depending on the make and model of your car.

Catalytic Converter: The catalytic converter is a device that uses a chemical reaction to convert exhaust gases into less harmful substances.

Oxygen Sensor: The oxygen sensor is located in the exhaust pipe and monitors the amount of oxygen in the exhaust.

Muffler: The muffler is a device that reduces noise from the engine.

Tailpipe: The tailpipe is the final component of the exhaust system. It’s a pipe that extends from the muffler to the exhaust tips.

Resonator: The resonator is a device that’s located between the catalytic converter and the muffler. It eliminates or reduces high-pitched sound frequencies before reaching the muffler.

Exhaust Tips: The exhaust tips are the final part of the exhaust system. They’re located at the end of the tailpipe and give the car’s exhaust a finished look.

Cost to Replace Each Part

Now that we know what is included in a full exhaust system, let’s look at the cost of replacing each part of an entire exhaust system, including parts and labor costs.
