How to Purchase an Exhaust for a Lexus RX

The main function of a car's exhaust system is to transport the combustion gases, also known as burned exhaust, from the engine to the outside, through a tail pipe. The tail pipe is a long tube that links the engine to the rear of a vehicle. Several components of a car are responsible for the proper function of the exhaust system. Different car types have different exhaust systems, and those looking to replace the exhaust of a Lexus RX should make sure to buy parts for that specific model of car.

There are many reasons to replace an exhaust system. The old Lexus RX exhaust may be broken, or the owner may simply wish to upgrade it. Upgrading to a performance exhaust allow the gases in the engine to escape more easily, thus freeing up some of the power of the engine. Regardless of the reason buyers are looking for a new Lexus RX exhaust, learning more about how the system works may help them find and purchase the right one.

What is an Exhaust System?

The exhaust system of a Lexus RX consists of a set of metal pipes that are essential for the vehicle to run safely and reliably. The exhaust is responsible for carrying away the toxic emissions generated by the combustion of gas that occurs when the engine is running. Most exhaust systems, including those designed for the Lexus RX, clean up the gases prior to releasing them into the environment. There are several different types of exhausts that can be used on a Lexus RX, and some of them allow the gases to flow more smoothly. This often boosts the performance and efficiency of the car.

Main Components of an Exhaust System

An exhaust system is comprised of several components. The primary parts include the exhaust manifold, the catalytic converter, the pipes, the muffler, and the tailpipe. All of these components work together to collect the exhaust gases from the engine and transport them to the outside. If something goes wrong with the exhaust system of a Lexus RX, the gases may become trapped, or they may leak out before all the dangerous substances are removed. Gas leakage may potentially create a safety hazard, especially if the gases enter the passenger area of the car.

When to Replace the Exhaust of a Lexus RX

Owners should repair or replace the exhaust system of a Lexus RX as soon as they notice a breakdown. In addition to that, they should check the exhausts periodically to discover any soot emissions. Soot emissions appear from time to time when the exhaust system is faulty and they may cause soot buildup that affects the catalytic converter. Diesel particulate filters can also be affected, and this can be harmful for the environment, since the main function of the filters is to stop the soot emissions from being released into the air.

This is the main reason car owners should do their best to keep the exhaust system of their Lexus RX in optimum condition. In most cases, it is enough to check the state of the exhaust once or twice a year and replace it after a few years. Some things to look out for when doing the annual check include the following:

  •     Traces of corrosion
  •     Leakages
  •     Soot from exhaust pipe, or
  •     Any other type of visible damage

Any of the types of damages enumerated here may deteriorate the durability of a Lexus RX and cause serious damage to the environment.

What to Watch out for when Shopping for a Lexus RX

Shopping for an exhaust for a Lexus RX may not always be as simple as it sounds. The choices are many and varied, and it can be difficult for buyers unfamiliar with such components to decide which one is the best for their car. Moreover, various modifications can be made to the existing exhaust system of a Lexus RX, which can boost the performance of the engine. By doing this, buyers can make certain the engine of their car operates at its maximum potential. Such modifications can include replacing pieces of the original exhaust system with upgraded parts, or simply smoothing the insides of the pipes.


Headers are a good choice for efficient car exhaust, but in many instances they can be expensive. This is also true of headers for the Lexus RX. However, the accessory can be customised according to the specifications of a certain vehicle, so buyers on a budget can opt for a cheaper one, and have it adapted to the Lexus RX.


Besides eliminating harmful gases, another function of the exhaust is to control noise. A silencer is a part of the exhaust system of a Lexus RX and it is linked to the engine by a series of pipes. The silencer is made of metal plates or tubes and it features a series of holes. When the exhaust gases leave the engine, they do so at very high pressures, which may cause disturbing noises. The holes in the silencer help to reduce the pressure and thus the gases are able to leave the care more quietly.

The silencer is actually the part of the exhaust system that is likely to fail first, because it is the furthest away from the engine, which means it is more prone to corrosion by acidic moisture. Car owners who hear roaring or rattling noises that were not present before may want to have the silencer checked out. If this is faulty, it may need immediate replacement.

When a Lexus RX owner decides it is time to purchase a new exhaust for their vehicle, they need to be absolutely sure the item they buy is suitable for their car type.
