5 Best Exhaust for Subaru WRX

The Best Exhaust for Subaru WRX is used to convert waste energy into useful low-velocity energy. It involves the conversion of high-pressure gas inside the combustion chamber to low-pressure gases which are then removed from the cylinder through exhaust valves.

A WRX Exhaust allows gases to escape from a controlled environment, which is normally the cylinder head.

The most important function of an exhaust system is to reduce noise pollution and increase fuel economy by allowing the engine to work at optimal conditions.

WRX Exhaust system is employed whenever there is an accumulation of harmful pollutants in the exhaust pipe such as Carbon monoxide (CO), which can cause serious health problems.

Good Exhausts are easy to install and should not cause any damage to other engine components such as manifolds, catalytic converters, or oxygen sensors.

Choosing Exhaust System for Subaru WRX – Complete Buying Guide

subaru WRX Exhaust

There are a lot of exhaust systems in the market when it comes to Subaru WRX. With so many brands, models, and variations you might get confused when looking for one.

It is not always a necessity to go for the most expensive one. You can find some great options under $500.

Here we will discuss some features and benefits you should look at before buying an exhaust system for Subaru WRX:


Mufflers are always considered as one of the most important parts of the exhaust system. A good muffler will not only reduce the noise and give you a great sound but also improve your car performance and mileage too. So, it is very important to go for a muffler whose diameter is at least 2.5 inches.

Catalytic Converter

A catalytic converter is required by law to be installed in all modern exhaust systems. The main function of the catalytic converter is to reduce the emissions which are harmful to the environment.

So, it becomes extremely important that you pick up an exhaust system that has a good quality catalytic converter. What is the use of spending money on an exhaust system if it does not fulfill your requirements?

Muffler Configuration

When we talk about mufflers, there are two types of them: 2-chamber and 4-chamber mufflers. The 4-chamber muffler has a better noise canceling capacity.

It will give you a nice sound and reduces the noise according to the amount of fuel your engine is burning. In short, these mufflers are more expensive but have a better performance too.


The next thing you should look for while buying an exhaust system is the pipe configuration. There are three types of pipes, merge, cross, and straight.

Merge type exhaust system is the best if you are looking for noise cancellation. Cross-type has a better performance than the other two, but it may give you a loud sound which can annoy some people.

Muffler Shape

The shape of the muffler is also an important thing which you should consider while buying an exhaust system.

For example, a muffler with a round shape will give you a nice look but it will not be able to cancel noise as much as a muffler with a square or rectangular shape can do.

Exhaust Tip

The most common and simplest tip comes with every exhaust system. It looks simple and it does not affect the performance of your car exhaust system.

There are some other options available as well such as colorful exhaust tips which you can consider if you want to stand out of the crowd or if this is allowed by law where you live.


The last thing but not the least is the quality of the exhaust system. You should not spend your hard-earned money on a cheap product that does not have any standard quality.

Always check the brand reputation before buying one. Some very famous brands are Magnaflow, Borla, Corsa, Flowmaster, etc.


The cost of the exhaust system is another factor which you should consider. As all the parts and components are not required same for different cars so the price will also differ accordingly.

If you want to buy an exhaust system for Subaru WRX, expect to spend around $400-$500 on it if your car is 4-Cylinder and if you have a 6-Cylinder engine in your car then it will cost you around $500-$600.


It is always advised to buy an exhaust system with a warranty. This way you can get your money back in case it does not work properly.

So, when buying an exhaust system make sure that the company provides at least 12 months or more warranty on the exhaust system.

Type of Vehicle Supported

The next important thing you should consider is whether the exhaust system is compatible with your car or not. If it is not, you will not be able to install it on your own and you will have to pay someone who can do it for you. So before buying an exhaust system make sure that it fits your vehicle type.


Last but not the least, you should always consider your budget before buying an exhaust system. You can buy a great upgraded exhaust for Subaru WRX for under $500 if you look properly.

Just make sure that the company provides good customer service and offers a warranty on their products.

Installation Time

Exhaust systems are not so hard to install. They usually take around 2 hours depending upon the type of exhaust system you have purchased.

So, if you want to save some money then it is better that you install it on your own rather than paying someone else for doing it.

Sound Quality

The main purpose of buying an exhaust system is to get rid of the annoying noise your car engine creates. So, you should always check out whether it cancels noise or not before buying it.

Some brands claim that their product has the lowest sound quality, but they just lie about it. So, if you want your money’s worth then you should do your research.



There are abundant exceptional possibilities when it comes to the exhaust systems, and all the above-stated exhausts are the Best Exhaust for Subaru WRX but if you had to pick one, I would very well recommend the BORLA 140595 Exhaust System.

Enjoy a higher horsepower without sacrificing tone with this best exhaust for your vehicle. This mandrel-bending technology will transform any WRX with deep resonances under acceleration, helping you get that extra power when needed most while also increasing fuel consumption in true STI style.

As a second choice, I would recommend the readers think about the SRS Axleback QUAD TIP Exhaust.

The enthusiasts who want to make their car louder and more powerful will find the perfect solution in this Exhaust for Subaru WRX. Made with deep tones, it decreases unwanted noise while increasing power by much like what you would expect from any other type or brand of the muffler.

Plus, it also includes polished durable finishing that gets rid of all scuff marks so there’s no need to worry about maintaining its appearance over time either. Installation couldn’t be easier either, thanks to its free-flowing system.
