The Complete Guide to Buying Car Exhaust Parts on eBay

A car's exhaust pipe and parts are used to simply guide a car's exhaust in a safe direction (as some of these gases are toxic and combustible), to reduce the pollutants in the exhaust, and also act to reduce noise. Car exhaust systems have many different small parts, and generally include an exhaust manifold, catalytic converter, and silencer. For this reason, car exhaust parts can be relatively expensive.

Those wishing to save on the cost of car exhaust parts are strongly encouraged to do their shopping via eBay, which can provide many such parts at reduced costs compared to retail prices. The wide variety of parts sold on eBay also means that shoppers may be more likely to find the parts they need without visiting several stores. Before purchasing parts, however, shoppers should ensure that they are familiar with the different parts, should understand the pros and cons of manufacturer vs. aftermarket parts, and are familiar with the tools required to work on the parts they purchase.

Car Exhaust Parts

Car exhaust parts are usually categorised based on the area of the system they belong to. In general, these include the exhaust manifold, the catalytic converter, and the silencer. Depending on a vehicle's age, it may not feature all of these parts. For this reason, shoppers should familiarise themselves with their own vehicle before shopping for parts, and thoroughly read their vehicle owner's manual concerning their vehicle's exhaust system. When shopping for car exhaust parts, the eBay software features organisational tools to allow individuals to quickly find exhaust parts in each of the categories below.

Exhaust Manifold Parts

A vehicle's exhaust manifold is the first step in a vehicle's exhaust system. A vehicle's exhaust manifold is the part of the exhaust which attaches to the cylinder head of the engine, guiding the air produced from the combustion cycle of the engine away, and combining the exhaust air from each of the separate cylinders into one pipe. Most exhaust manifolds are manufactured of steel or cast iron, though some aftermarket manufacturers spray fine ceramic over the steel, which acts to improve performance, longevity, and ease of cleaning.

Exhaust Manifold Gaskets

Exhaust manifold gaskets attach between the manifold ports and the engine, and serve to maintain adequate pressure. These gaskets are meant to be airtight, and should be replaced over the life of a vehicle. They are relatively small and inexpensive.

Oxygen Sensors

Oxygen sensors are generally added to the exhaust system at the tail end of the exhaust manifold pipes, and serve to measure the air-to-fuel ratio produced by the engine. This is used to calculate pollution rates, and to determine the relative efficiency of the engine.

Catalytic Converter Parts

The catalytic converter is the area in the exhaust system which is responsible for eliminating many of the pollutants found in exhaust air. In some areas, a vehicle may be illegal to operate without a properly fitted and functioning catalytic converter.

Catalytic Converter Clamps and Hangers

A vehicle's catalytic converter is generally a large box which attaches to the end of the cylinder head. Though the catalytic converter itself is generally self-contained, there are several clamps and at least one hanger which are used to hold it firmly and safely in place along the car's underside. Though the catalytic converter hanger is generally specialised to the task, any clamps used are often interchangeable with clamps used elsewhere along the exhaust system.

Silencer Parts

The silencer, sometimes also known as a muffler, is generally the last part of a car exhaust system, and is responsible for reducing the noise produced by an exhaust system and engine. The silencer is one of the larger and heavier mechanical components in a car, and usually needs replacing under a wide variety of circumstances.

Silencer Clamps

The silencer is arguably the heaviest part of a car exhaust system. For that reason, clamps are used liberally along it, to ensure it hangs securely from the underside of the vehicle. Clamp failure can be devastating, quickly ruining the silencer, and potentially attached parts or other elements of a vehicle.

Silencer Connecting Pipe

A vehicle's connecting pipe simply connects the silencer to the tailpipe, and is contoured specific to the make, model, and year of a vehicle to accommodate other elements along the underside of the vehicle. When purchasing a connecting pipe, shoppers should ensure that the part is able to fit both the silencer and the tailpipe.

Silencer Tailpipe

The silencer tailpipe forms the very end of a car's exhaust system, and is held in place by a final clamp. Many users switch out their factory tailpipes for aftermarket options.

Manufacturer vs. Aftermarket Car Exhaust Parts

Many of the parts in a car's exhaust system can be purchased either via the vehicle's manufacturer or through aftermarket manufacturers. There are many pros and cons associated with purchasing one or the other, and individuals should weigh their options critically before coming to a decision.

Manufacturer Car Exhaust Parts

Manufacturer car exhaust parts have one outstanding benefit to users: They are manufactured specifically for each different vehicle, and they are guaranteed to operate correctly. Manufacturer car exhaust parts are also typically easy to find and order. However, depending on a car's make, model, or year, one of the biggest cons to ordering manufacturer parts is their expense. For many vehicles, manufacturer parts are oftentimes prohibitively expensive, especially for higher-end vehicles. Many shoppers turn to eBay for manufacturer parts in hopes of finding them listed at cheaper prices. However, shoppers should be warned that in some cases, if a vehicle is old enough, the manufacturer may no longer produce the specific parts needed.

Aftermarket Car Exhaust Parts

Aftermarket car exhaust parts are manufactured by third-party vendors, and are generally cheaper than manufacturer options. However, because aftermarket options are not manufactured specifically for a car's make and model, there may be minute size and fitting differences which can cause unforeseen difficulties if users do not measure or source their parts properly. In the case of newer cars, the use of aftermarket parts rather than manufacturer parts may actually void any existing warranties.

Performance Aftermarket Exhaust Parts

Performance aftermarket exhaust parts are in their own tier, because they are often made to specifications more exacting even than manufacturer parts. These are generally the most expensive options available to shoppers, and they designed to be super effective and ultra-stable. These are generally only applied to performance or sport vehicles. But those searching for these ultra-specialised parts may find them at discount prices via eBay.

Most Common Car Exhaust Tools

There are several tools and equipment required to repair, replace, or test the various elements of a car exhaust system. For a quick overview of those tools and equipment, consider the chart below.
