An efficient exhaust system is essential for a vehicle’s performance and safety. However, some parts of the exhaust system are particularly expensive to replace and a failed part can result in a hefty repair bill. Here are six exhaust system parts that are expensive to replace and how they can break.
1. Catalytic Converter
The catalytic converter is a critical component of the exhaust system that converts harmful emissions into less toxic substances. If the catalytic converter is faulty, it can cause problems such as reduced engine performance and increased emissions, not to mention bothersome dashboard warning lights.
Because they are often made from platinum, replacing a faulty catalytic converter can be a costly job, with replacement costs ranging from one to several thousand dollars.
Catalytic converters can fail due to issues such as contamination, overheating and clogging. If the catalytic converter on your car or truck needs repair, keep in mind that it may be a covered expense under New York lemon law.
2. Exhaust Manifold
The exhaust manifold collects exhaust gases from the cylinders and directs them into the exhaust system. If the exhaust manifold is faulty, it can cause problems such as reduced engine performance, increased noxious emissions, and high-volume carbon monoxide leaks into the cabin.
Replacing a faulty exhaust manifold can be a costly repair, with replacement costs ranging from several hundred to a thousand dollars or so.
Exhaust manifolds can fail due to issues such as corrosion, worn gaskets, and cracks from overheating. Be certain to replace or repair this part to avoid breathing carbon monoxide as you drive.
3. Muffler
The muffler is responsible for reducing the noise produced by the engine. If the muffler is faulty, it can cause problems such as intense noise, reduced engine performance, and noxious leaks.

Replacing a faulty muffler can be a costly repair, with replacement costs ranging from several hundred to several thousand dollars depending on whether other parts need replacement at the same time, such as the exhaust pipe. Mufflers can fail due to issues such as salt corrosion, overheating, and weld failure.
4. Exhaust Pipe
The exhaust pipe is responsible for directing exhaust gases from the muffler to the tailpipe. If the exhaust pipe is faulty, it can cause problems such as reduced engine performance, increased emissions, and leaks.
Replacing a faulty exhaust pipe can be expensive due to the welding involved, with replacement costs ranging from a couple hundred to a thousand dollars. Exhaust pipes can fail due to overheating or from hitting speedbumps or other obstacles.
5. Oxygen Sensor
The oxygen sensor is responsible for monitoring the oxygen levels in the exhaust gases, which is essential for ensuring proper engine operation. If the oxygen sensor is faulty, it can cause reduced engine performance and increased emissions.

Replacing a faulty oxygen sensor can cost several hundred to several thousand dollars, depending on the materials and brand. Oxygen sensors can fail due to overheating or clogging due to faulty cylinders.
6. Tailpipe
The tailpipe is responsible for directing exhaust gases out of the vehicle. If the tailpipe is faulty, it can cause problems such as reduced engine performance, increased emissions, and leaks. Replacing a faulty tailpipe can be costly due to the welding involved. This repair can cost a couple hundred to a thousand dollars if it’s a designer piece. Tailpipes can fail due to salt corrosion and collisions.
The exhaust system is an essential component of a vehicle, and some parts are particularly expensive to replace. Understanding how these parts can break and the associated replacement costs can help vehicle owners make informed decisions about their vehicles, ensuring a smooth and hassle-free ownership experience.
