How Exhaust System Works
A typical exhaust system will consist of several components, with the key ones being the manifold, catalytic converter, mufflers, exhaust pipes, tailpipe, and exhaust tips.

In this setup, the exhaust manifold acts as a funnel that collects the exhaust gases from the cylinder head. The gases then move to the catalytic converter, a small metal chamber that helps reduce emission by altering the exhaust gases' composition.
From the catalytic converter, the gases move to a resonator. This component reduces some of the noise before the gases pass to the muffler, which further cuts down the noise. The exhaust gases then exit through the tailpipe, which is the last part of the system.

Anyone with at least basic mechanic skills can install this exhaust thanks to the easy bolt-on installation design. Also, you get more precise vehicle fitment.

2. Best Budget Exhaust System: Dynomax 17340
For motorists shopping for a more budget-friendly exhaust system, the Dynomax 17340 is unbeatable. But, despite being a budget model, it is still well-built and with a lot to offer.
One of its key highlights and why it has a spot on our best aftermarket exhaust systems list is the large internal flow tubes that improve the exhaust flow and reduce back pressure. What's more, there is a unique flow director design that helps eliminate turbulence and channel exhaust flow.
The mufflers on the system use fiberglass matting technology to absorb the unwanted interior resonance and ensure the exhaust maintains a mellow performance tone. Motorists also love the bolt-on installation as it makes mounting a breeze.
The kit seems to be missing some crucial components like pipe nuts for the catalytic converter adapter, but these are easy to get locally. Also, the tips' quality is not the best, but for this system's price, that is a small issue you can overlook.
Pros:
- Ideal for tight budgets
- Improved exhaust flow with minimal backpressure
- Mufflers absorb unwanted resonance
- Maintains a mellow performance tone

What's more, it has a full bolt-on fitment to ensure you have an easy time and speed up the job when it comes to installation.

Pros:
- Highly impressive sound output
- Well-built and durable
- Easy installation
- Dyno tuned for maximum performance
Cons:
- Tailpipes can be hectic to mount
4. Best Dual Exhaust System: Borla 140595

You can buy this product with confidence that you will get value for money as it is guaranteed to last at least a million miles.

Pros:
- Straight through design for maximum performance
- Excellent sound output
- Provides more accurate fit
- Guaranteed to last a million miles
Cons:
- Tips are not entirely straight

The few drawbacks of this system include the fact that it has a droning noise from inside the car, but the sound only takes a little getting used to. Also, the wanting sound at low RPM should not be a deal-breaker given its overall performance.
Pros:
- Provides accurate and precise fit
- Tough and durable materials
- Adds power and improves fuel economy
- Maximum flow with ultra-smooth bends
Cons:
- Tends to have a droning noise from inside the car

How to Buy the Best Exhaust Systems
1. Compatibility
For any exhaust system to serve you well, it first needs to fit your vehicle. Hence, the first factor to consider when deciding on the model to buy is its compatibility with your car.
When it comes to compatibility, you need to check the vehicle model and year the particular exhaust is made to fit. Also, check engine size it works to ensure it can work for you.
But also note there are some universal fit exhaust systems like the Flowmaster 817674 that can work for almost any vehicle out there.
2. Types of Exhaust System
Header Back
The header-back exhausts typically have a single piece and with the header collector being the starting point, while the tailpipes are the endpoints. These exhausts are a complete system that replaces almost all stock exhaust system components. The simple design and the fact that header-back exhausts are simple to install makes them highly popular.
Cat Back
Cat-back exhaust systems have a long or short pipe for different vehicle models, and they typically include a muffler. Despite being more competitively priced than other types, these exhaust systems offer superior performance. Cat-back is also the best option when you do not want to replace your catalytic converter when installing the exhaust system.
Axel Back
The axel-back exhaust systems are similar to the factory or conventional exhaust system in appearance. They produce a deeper sound making them popular with motorists that prefer loud exhaust systems. Also, they tend to be more affordable, and hence an excellent choice for budget shoppers.
3. Performance and Sound
The actual performance you get from the exhaust system matters a lot as it is one of the key reasons you are buying it. Something that reduces pressure significantly is always the best as it leads to power gain and improves the fuel economy.
When it comes to the sound, it is often a matter of personal preferences as some will deliver a loud and deep engine sound while others tend to suppress the sound for quieter rides.
4. Construction
Crush Bends
As the name suggests, crush bend exhaust systems are those bent by exerting pressure at specific spots. The simple technique used to bend this exhaust makes it relatively more affordable. But, compared to the mandrel, these exhausts vibrate more and are hence low performers.
Mandrel Bends
Mandrel bend exhausts get their bends from a bending die as they pass through a hydraulic press. However, a mandrel is also added inside the tube to ensure it retains its shape. Hence, the pipe ends up with a more uniform diameter throughout its length.
Exhausts that use these bends are typically high performers as they vibrate less and are more durable. However, mandrel bend exhausts are more expensive.
5. Style
You will also need to decide on the exhaust style you prefer, and here the two main options are single and dual systems.
Single
Single exhaust systems like Dynomax 17340 feature one set of pipes, a single muffler, and in most cases, they have just one tailpipe and tip. With these exhaust systems, you can be sure of getting more power, decent torque gain, and significant fuel economy gains. Additionally, they are easy to mount as no welding or cutting is required.
Dual
With the dual types such as Flowmaster 817692, you get a pair of exhaust pipes, two mufflers, and two tips. These exhausts either exit on each side of the vehicle or at one point below the bumper. What makes the dual exhaust systems great is that they provide serious torque and power gains.
6. Material
The material used to make the exhaust system is vital as it determines both the appearance and durability. Although modern exhaust systems use various material types, mild steel and stainless steel are the most common ones.
Stainless steel exhausts are more durable and offer greater resistance to rust or corrosion. What's more, they have a pleasant look. However, stainless steel exhausts are more expensive.
Mild steel ones are more affordable and are often what many motorists turn to when looking for a new exhaust system. But, they are not resistant to corrosion and are also not very aesthetically appealing.
7. Ease of Installation
It would be nice to install the exhaust system yourself without incurring an extra cost to pay a mechanic for the job. However, for this to be possible, the exhaust you choose needs to be easy to install.
Models that come with all the components you need and some clear, step-by-step directions on what to do, give you the easiest time when it comes to DIY installation.
